Prescription Opioids Play Only Minor Role in Overdose Crisis

By Pat Anson, PNN Editor

The role of prescription opioids in the nation’s overdose crisis continues to shrink.

In a new study from the drug testing firm Millennium Health, researchers say multiple substances were found last year in nearly 93% of urine samples in which fentanyl was detected. That is not altogether surprising, as “polysubstance” use increased as fentanyl came to dominate the illicit drug supply, appearing in more and more street drugs such as heroin, cocaine and methamphetamine.

What is surprising is the minimal role that prescription opioids now play. In 2013, opioid pain medication was the most common substance found in fentanyl-positive drug tests in the United States, appearing in over 70% of urine samples.  A decade later, prescription opioids were detected in less than one in ten samples — ranking far behind methamphetamine, cannabis, cocaine and heroin.

In fact, you are about twice as likely to find two other medications -- benzodiazepines (15.8%) and gabapentin (13.3%) -- than you are prescription opioids (7.6%) in urine samples testing positive for fentanyl.

Substances Detected in Fentanyl-Positive Drug Tests (2023)

Millennium based its findings on over 4.1 million urine drug tests (UDTs) collected from 2013 to 2023 and analyzed through mass spectrometry. Because many of those samples came from people being treated for a substance use disorder, they offer a clear insight into drug trends that are driving the overdose crisis.

Now in its “fourth wave,” Millennium says a tidal shift has occurred in the so-called opioid epidemic, with illicit drug users far more likely to use non-opioid substances like stimulants than prescription opioids.

“National, regional, and state-level UDT data all suggest that people who use fentanyl are now, intentionally or unintentionally, much more likely to also use methamphetamine and cocaine,” the report found. “The results of our analyses also reveal shifting patterns of opioid use among those who use fentanyl. More specifically, they showed progressive declines in prescription opioid use from 2015 to 2023.”

The declining role of prescription opioids can be traced back to the 2016 CDC opioid guideline and a multiyear campaign by the DEA to slash opioid production quotas, which has reduced the supply of oxycodone and hydrocodone by about two-thirds. There is little evidence either of those federal efforts reduced the number of overdoses. The CDC estimates there were over 111,000 drug deaths in the 12-month period ending in September 2023 — nearly double the number of fatal overdoses in 2016.

The growing use of stimulants such as methamphetamine makes it difficult for public health campaigns to address the problem. Unlike opioids, there are no FDA-approved medications for stimulant use disorder, leaving behavioral therapies and abstinence as the only “evidence-based” treatments for people with a stimulant problem.

“Stimulants are a serious national challenge emphasizing the need for continued progress on the national plan to address methamphetamine supply, use, and consequences,” Millennium said.

Stimulants Involved in Growing Number of Fentanyl Overdoses

By Pat Anson, PNN Editor

The number of drug deaths involving both fentanyl and stimulants has soared in recent years, according to a new UCLA study that highlights the complex and changing nature of the U.S. overdose crisis.

Stimulants such as cocaine and methamphetamine are now involved in nearly a third of fentanyl-related overdoses, the most of any other drug class. Fentanyl is a synthetic opioid up to 100 times more potent than morphine and 50 times as potent as heroin.

In 2010, researchers say there were only 235 fatal overdoses in the U.S. involving illicit fentanyl and stimulants. In 2021, there were 34,429 drug deaths linked to fentanyl and stimulants, a 14,550% increase in a little over a decade.

"We're now seeing that the use of fentanyl together with stimulants is rapidly becoming the dominant force in the US overdose crisis," said lead author Joseph Friedman, PhD, an addiction researcher at the David Geffen School of Medicine at UCLA. "Fentanyl has ushered in a polysubstance overdose crisis, meaning that people are mixing fentanyl with other drugs, like stimulants, but also countless other synthetic substances. This poses many health risks and new challenges for health care providers.

“We have data and medical expertise about treating opioid use disorders, but comparatively little experience with the combination of opioids and stimulants together, or opioids mixed with other drugs. This makes it hard to stabilize people medically who are withdrawing from polysubstance use."

People who overdose on stimulants and other non-opioid substances mixed with fentanyl may not be as responsive to naloxone, which only works as an antidote to opioids.

The study findings, published in the journal Addiction, highlight the four “waves” of the overdose crisis, which began with an increase in deaths from prescription opioids (Wave 1) in the early 2000s, followed by a rise in heroin deaths (Wave 2) in 2010, and fentanyl-related overdoses in 2013 (Wave 3). The fourth wave — overdoses from fentanyl and stimulants — began in 2015 and continues to escalate.

The Four Waves of Overdose Crisis

SOURCE: ADDICTION

Since cocaine, methamphetamine and other stimulants are not opioids, the findings undercut the long-held theory that the overdose crisis started with prescription opioids and is still being fueled by people addicted to them. Deaths involving prescription opioids and heroin have been in decline for several years.

Researchers found that fentanyl/stimulant deaths disproportionately affect African Americans and Native Americans. There are also geographical patterns to fentanyl/stimulant use. In the northeast US, fentanyl is usually combined with cocaine, while in the south and western US, fentanyl is most commonly found with methamphetamine.

"We suspect this pattern reflects the rising availability of, and preference for, low-cost, high-purity methamphetamine throughout the US, and the fact that the Northeast has a well-entrenched pattern of illicit cocaine use that has so far resisted the complete takeover by methamphetamine seen elsewhere in the country," Friedman said.

In addition to its low cost, drug users say methamphetamine helps prolong fentanyl’s “high” and delays the onset of withdrawal symptoms.  

Counterfeit pills laced with fentanyl – which are frequently made to look like oxycodone or alprazolam (Xanax) – represent about a quarter of all illicit fentanyl seizures. Researchers say it is difficult to track deaths involving counterfeit pills because they are often mistaken for legitimate medication, so the data is not completely reliable.

In its most recent update on the overdose crisis, the CDC estimates there were a record 111,355 drug deaths in the 12-month period ending April 2023 -- about a thousand more deaths than the year before. Fentanyl and its analogues were involved in nearly 70% of the overdoses, stimulants were linked to about a third of them, and cocaine was involved in about a quarter of the drug deaths.

CDC Study Shows Oxycodone Plays Minor Role in Overdose Crisis

By Pat Anson, PNN Editor

A new study by the CDC highlights the sharply rising death toll in the U.S. caused by illicit fentanyl, while at the same time revealing the minor role played by oxycodone in the nation’s overdose crisis.

The study, released this week by the CDC’s National Center for Health Statistics, looked at overdose death rates from 2016 to 2021. Deaths involving fentanyl more than tripled during that period, rising from 5.7 deaths per 100,000 people in 2016 to 21.6 deaths per 100,000 in 2021. Drug deaths involving methamphetamine and cocaine also rose sharply, while fatal overdoses involving heroin declined.

And what about oxycodone, the most commonly prescribed opioid pain medication? It turns out oxycodone has always played a relatively minor role in the overdose crisis, although regulators and public health officials said otherwise in a concerted campaign against all prescription opioids.

“Overprescribing opioids – largely for chronic pain – is a key driver of America’s drug overdose epidemic,” then-CDC director Dr. Thomas Frieden said in a 2016 news release.

But the facts don’t support Frieden’s claim. In 2016, the year the CDC released its controversial opioid prescribing guideline, there were only 1.9 deaths per 100,000 people that involved oxycodone. By 2021, the rate had fallen 21% to 1.5 deaths -- well below the death rates of fentanyl, methamphetamine, cocaine and heroin.   

Drug Overdose Deaths in U.S. (2016-2021)

CDC researchers used an unusual method to conduct this study. Instead of relying on medical ICD-10 codes in death certificates, which lump drugs together into broad categories, the CDC used a “literal text” analysis.

“To address the limitations of ICD–10- coded mortality data, the National Center for Health Statistics has developed a method that searches the literal text of death certificates to identify mentions of specific drugs and other substances involved in the death. Death certificate literal text is the written information provided by the medical certifier, usually a medical examiner or coroner for drug overdose deaths, that describes the causes, manner, and circumstances contributing to the death,” the researchers explained.

Flawed Data

The literal text method is not foolproof, but it’s an improvement over the ICD-10 codes, which the CDC admitted in 2018 “significantly inflate” the number of deaths involving prescription opioids — flawed data that Frieden used to make his “key driver” of the epidemic claim in 2016.

How inflated were the overdose numbers back then?  Using the old ICD-10 method, which counted illicit fentanyl as a prescription opioid, Frieden’s CDC estimated that nearly 32,500 Americans died from overdoses of opioid medication in 2016. The death toll was later revised downward to about 17,000 overdoses after the CDC came clean about its flawed methodology.

Patient advocate Richard “Red” Lawhern has long been suspicious of CDC data, including studies that use literal text analysis.  

“CDC suggests an incidence of drug overdose deaths ‘involving’ oxycodone at only 1.5 per 100,000.  But they neatly avoid telling us that such a rate is so low that it confounds the non-uniformity of reporting from county to county, creating such statistical noise that the contribution of this agent (oxycodone) to overdose mortality is too small to accurately measure or report,” Lawhern said.  

Another problem is the qualifications of county coroners and medical examiners varies. Some are elected to their positions without any medical training or experience. The death certificates they fill out usually don’t say if a prescription drug was obtained legally or illicitly, or what specific drug or combination of substances caused the death. That is determined later by a toxicology test. As a result, a drug may be “involved” in a death and be listed on the death certificate, but have little or nothing to do with someone’s demise.

“It is startling that CDC has so consistently and deliberately conspired to disguise the fact that oxycodone really isn't significant in drug overdose mortality, and probably never has been,” Lawhern told PNN. 

Of course, every death is a tragedy in some way, regardless of the cause or substance involved. The graphic below helps bring oxycodone’s role into more context – comparing the five leading causes of death in 2021 to those involving fentanyl, oxycodone and the other drugs.

Despite the minor role played by oxycodone in 2021 deaths, efforts continue to restrict its availability. This year the Drug Enforcement Administration reduced the supply of oxycodone for the seventh consecutive year. Since their peak in 2013, DEA production quotas for oxycodone have fallen by 65 percent. The tightened supply has resulted in recent reports of oxycodone shortages and patients unable to get their prescriptions filled.

The DEA justifies the cuts by saying it is concerned about diversion and abuse, but the agency’s own data shows that less than one percent of legally prescribed oxycodone (0.3%) is diverted to someone it was not intended for.

Drug Tests Show Pain Patients on Opioids Less Likely to Use Illicit Drugs

By Pat Anson, PNN Editor

In an effort to reduce soaring rates of drug abuse and overdoses, many physicians have taken their pain patients off opioids and switched them to “safer” non-opioid drugs like pregabalin, gabapentin and duloxetine. Others have encouraged their patients to try non-pharmacological treatments, such as acupuncture, massage and meditation.

That strategy may be backfiring, according to a large new study by Millennium Health, which found that pain patients prescribed opioids are significantly less likely to use illicit drugs than pain patients not getting opioids.

The drug testing firm analyzed urine drug samples from 2019 to 2021 for nearly 55,000 patients being treated by U.S. pain management specialists. About 80% of the patients were prescribed an opioid like oxycodone or hydrocodone, while the other 20% were not prescribed opioids.

Millennium researchers say detectable levels of illicit fentanyl, heroin, methamphetamine and cocaine were far more likely to be found in the urine of non-opioid patients than those who were prescribed opioids. For example, illicit fentanyl was detected in 2.21% of the patients not getting an opioid, compared to 1.169% of those who were. The findings were similar for heroin, methamphetamine and cocaine.

“In all cases, we found that the population that was not prescribed an opioid was significantly more likely to be positive for an illicit drug than those patients who were prescribed opioids,” said lead author Penn Whitley, Director of Bioinformatics at Millennium. “(There was) a 40 to 60 percent increase in the likelihood of being positive if you were not prescribed an opioid.”

Illicit Drug Use By Pain Patients

MILLENNIUM HEALTH

What do the findings mean? Are pain patients getting ineffective non-opioid therapies so desperate for relief that they’re turning to illicit drugs? That’s possible, but the study doesn’t address that specifically.

Another possibility is that patients on opioids are simply being more cautious and careful about their drug use. Opioid prescribing in the U.S. has fallen by 48% over the past five years, with many patients being forcibly tapered or abandoned by doctors who feel pressured to reduce their prescribing.  

“Unfortunately, a lot of people with chronic pain have learned that it’s a bit tenuous, that their doctors are feeling pressure, and if they want to maintain their access (to opioids), they need their PDMP (Prescription Drug Monitoring Program) and their drug tests to look the way they need to look, so their doctor can feel comfortable continuing to prescribe,” said co-author Steven Passik, PhD, VP of Scientific Affairs and Head of Clinical Data Programs at Millennium. “I do think they realize that they’re on a treatment and that access to it is not guaranteed.”   

Preliminary findings from the study were released today at PainWeek, an annual conference for pain management providers. The findings mirror those from another Millennium study earlier this year, which found that pain patients have lower rates of illicit drug use than patients being treated by other providers.     

“If your main way of protecting people in pain from getting involved in substance abuse is to limit their access to opioids, there’s at least a hint here that’s not the right approach,” Passik told PNN. “It’s not a definitive statement by any stretch of the imagination, but it’s an approach to patient safety that leaves a bit to be desired.”  

Another recent study at the University of Texas also found that restricting access to opioids is “not a panacea” and may even lead to more overdoses.  Researchers found that in states that mandated PDMP use, opioid prescribing decreased as intended, but heroin overdose deaths rose 50 percent.

“Past research has shown that when facing restricted access to addictive substances, individuals simply seek out alternatives rather than limiting consumption,” said lead author Tongil Kim, PhD, an assistant professor of marketing at University of Texas at Dallas. “In our case, we measured overdose deaths as a proxy and found a substantial increase, suggesting that the policy unintentionally spurred greater substitution.”

Pain Patients Have Low Rates of Illicit Drug Use

By Pat Anson, PNN Editor

Anti-opioid activists have long claimed that opioid medication is a gateway drug to heroin and other street drugs. That myth is so ingrained in the medical community that many pain patients are discriminated against by doctors and pharmacists, who suspect they are abusing their medication or using illicit drugs.

But a large new study by Millennium Health pokes a hole in that myth, finding that patients being treated in pain management practices are far less likely to use heroin, fentanyl, cocaine and methamphetamine than other patients.

The drug testing firm analyzed the lab results of two million urine tests from 2015 to 2021 – nearly 600,000 coming from pain patients -- and found that patients seeing primary care physicians, behavioral health doctors (psychiatrists and psychologists), or getting substance use disorder (SUD) treatment were significantly more likely to test positive for street drugs than patients of pain management providers.

SOURCE: MILLENNIUM HEALTH

“That’s one of the reasons why we decided to put this out there in the public domain, because it’s important. Because clearly there are differences across these groups,” said Eric Dawson, PharmD, Vice President of Clinical Affairs at Millennium Health.

For example, the positivity rate for fentanyl in urine samples is about 2% for pain management patients – a level that remained stable throughout the 6-year study period.

But Millennium found that for primary care and behavioral health patients, the positivity rate for fentanyl has ticked up to about 5 percent.

In patients getting SUD treatment, the positivity rate has skyrocketed to about 17 percent, no doubt a reflection of the growing presence of illicit fentanyl in street drugs.

Positivity rates for methamphetamine are also rising for most patients – but not for pain patients – while cocaine use has remained relatively flat. Positivity rates for heroin have declined steadily for all patients since 2015, according to Millennium.

“Generally speaking, the pain population that’s treated with opioids is an older population and uses illicit drugs at a very low rate,” said Steven Passik, PhD, VP of Scientific Affairs and Head of Clinical Data Programs at Millennium.

“Not only are they low, they remain low,” says Dawson. “So many of the other groups, over time their positivity rates are increasing. The pain population started low and remains low. And that says they are different than the other groups.”

What makes the findings even more striking is that they include the first two years of the covid pandemic, a time when stress, isolation and depression led many people to abuse drugs.

“But that did not happen in the pain patients. You can actually see that,” says Passik, who believes regular drug testing makes pain management patients less likely to take risks that might affect their healthcare. He thinks the Millennium study should be reviewed by both providers and policymakers to get a better understanding of people in pain.

“There isn’t that much data like this out there. I think it’s unique and very positive about this population. And I think that should be factored in when people are talking about access to opioids,” Passik told PNN.

In addition to fentanyl, heroin and other street drugs, the Millennium study also looked at positivity rates for marijuana, which have soared in recent years due to the legalization of medical and recreational cannabis in many states. By the end of 2021, the positivity rate for cannabis had reached nearly 32 percent for most patients. But, like the other drugs, cannabis use remained relatively low for pain patients.  

Focus on Opioid Crisis Overlooks Rise in Stimulant Deaths

By Pat Anson, PNN Editor

While much of the nation was focused on the opioid crisis, new research shows that another drug epidemic was taking the lives of U.S. military veterans.

University of Michigan researchers say the rate of veteran overdose deaths involving cocaine, methamphetamine and other stimulants tripled from 2012 to 2018. Most of the veterans did not receive any substance abuse treatment in the year before they died.

“We have been so focused on opioids that we are missing the tremendous increase in people who are using multiple substances, as well as those using stimulants only, when we know that many people don’t stick to just one substance,” says lead author Lara Coughlin, PhD, a psychologist and an assistant professor in the U-M Department of Psychiatry. “The fact that so many of those who died of an overdose had not received substance use disorder treatment is especially concerning.”

Coughlin and her colleagues reviewed the medical records of 3,631 veterans who died from overdoses involving stimulants, and found that about two-thirds of the deaths involved cocaine. Over half of the stimulant deaths (54.1%) also involved another substance, usually alcohol or an illicit opioid such as heroin or fentanyl. Prescription opioids were involved in less than 26% of the stimulant-related overdoses.

Researchers called the tripling of stimulant deaths “an escalating public health crisis” that deserves more attention.

“Recent trends show stark increases in stimulant-involved overdoses, with the majority of these overdoses deaths involving multiple classes of substances. These more complex, polysubstance-involved overdose deaths necessitate an expansion from a singular opioid-centric focus to include other substances and consideration of the role of stimulant use on overdose risk to inform effective prevention and treatment efforts,” researchers reported in the journal Addiction.

The authors noted there are few medication-based treatments to help people reduce their use of methamphetamine or cocaine, while multiple medications are available to treat those with opioid or alcohol use disorders.

Better access to treatment was especially needed for veterans in rural areas and those who are homeless. About one-third of all the overdose deaths involving stimulants were in Black veterans, as were two-thirds of the deaths from cocaine alone.

In addition to the risk of overdose, researchers say people who use methamphetamine or cocaine are at greater risk of heart damage. About 62% of the overdoses involving stimulants were among veterans aged 45 to 64.

“We need to build better awareness of the role of stimulants as a risk factor for overdose, and of the need for those who have stimulant use disorders to be referred for treatment, regardless if they are also using opioids,” said Coughlin. “We know that cocaine and methamphetamine are much more likely to be adulterated with fentanyl or other synthetic opioids now, so those who use them need to be equipped with rescue doses of naloxone to use and need to know about the risk for overdose in case they or someone they’re with experiences an unexpected, life-threatening reaction.”

The rise in stimulant deaths has not occurred in a vacuum. In the first half of 2019, data from 24 states and the District of Columbia showed that stimulants were involved in 5 out of 11 fatal overdoses. The CDC issued a Health Alert Network Advisory last year about a record number of overdoses, due in part to an acceleration in stimulant-related deaths.

Nearly 85% of U.S. Overdose Deaths Linked to Street Drugs

By Pat Anson, PNN Editor

A new report by the Centers for Disease Control and Prevention shows that the vast majority of drug overdose deaths in the United States involve illicit fentanyl and other street drugs.  

The study, reported in the CDC’s Morbidity and Mortality Weekly Report, analyzed data from 24 states and the District of Columbia enrolled in the State Unintentional Drug Overdose Reporting System (SUDORS) from January to June, 2019. SUDORS captures detailed information from toxicology reports and death scene investigations, and is considered more reliable than overdose data gathered from death certificates.

Among the 16,236 overdose deaths reported by SUDOR during the study period, illicitly manufactured fentanyl (IMF), heroin, cocaine or methamphetamine were involved 83.8% of deaths, either alone or in combination with other drugs. Nearly half of those deaths involved two or more illicit drugs.

About one in five overdoses involved prescription opioids such as hydrocodone, oxycodone, morphine and buprenorphine. The study did not indicate whether the medication was obtained legally or if it was borrowed, stolen or purchased illicitly. What is clear, however, is that street drugs are the primary driver of the U.S. overdose crisis.

“The finding of this report that nearly 85% of overdose deaths involved IMFs, heroin, cocaine, or methamphetamine reflects rapid and continuing increases in the supply of IMFs and methamphetamine, coupled with illicit co-use of opioids and stimulants,” researchers reported.

More than two thirds (68.5%) of overdose victims were male, and over half (53.3%) were 25 to 44 years of age; demographics that don’t fit the profile of most chronic pain patients, who are generally older and female.

NBER Report Blames Rx Opioids

The new CDC report is at odds with a working paper recently published by the National Bureau of Economic Research (NBER), a non-profit, private think tank. The NBER report largely blames prescription opioids for the U.S. overdose epidemic – not street drugs or so-called “deaths of despair” caused by rising social isolation and economic distress.  

“People have blamed all sorts of things, heroin from Mexico and fentanyl from China and economic decline and so on and so forth,” co-author Janet Currie, PhD, a professor of economics at Princeton University, told Yahoo Finance. “But really the issue is that a whole lot of people got addicted because they were prescribed pain medications which aren’t prescribed in the same way in other countries.”

Currie and co-author Hannes Schwandt, PhD, an economics professor at Northwestern University, say pharmaceutical companies aggressively marketed opioids at a time when doctors were being encouraged to treat pain as “the fifth vital sign.”

“We argue that the development and marketing of a new generation of prescription opioids sparked the epidemic and that provider behavior is still helping to drive it,” the NBER report states. “Prior to the marketing push, most doctors had believed that opioids were too addictive and dangerous for anyone except terminally ill patients. Aggressive marketing by pharmaceutical companies changed those perceptions: Sales of opioid pain killers quadrupled between 1999 and 2013, fueling the rise in overdose deaths.”

What Curry and Schwandt fail to mention is that opioid prescriptions have fallen by nearly 40% since 2013. And their report only briefly mentions the rising toll taken by illicit fentanyl and other street drugs.

Fatal drug overdoses fell in 2018, for the first time in nearly 30 years, but many signs indicate they are rising again and that the COVID-19 pandemic is making the crisis worse in the U.S. and Canada.   

Canada’s Chief Public Health Officer recently warned the pandemic is fueling another surge in drug deaths in Canada.

“Tragically, in many regions of the country, the COVID-19 pandemic is contributing to an increase in drug-related overdoses and deaths,” Dr. Theresa Tam said in a statement. “There are indications that the street drug supply is growing more unpredictable and toxic in some parts of the country, as previous supply chains have been disrupted by travel restrictions and border measures. Public health measures designed to reduce the impact of COVID-19 may increase isolation, stress and anxiety as well as put a strain on the supports for persons who use drugs.”

DEA: Fentanyl 'Primary Driver' of Overdose Crisis

By Pat Anson, PNN Editor

The U.S. Drug Enforcement Administration has released the 2019 National Drug Threat Assessment, a comprehensive report that outlines the threats posed to the nation by drug traffickers and the abuse of illicit drugs.

Not surprisingly, the annual report found that illicit fentanyl is the “primary driver” behind the overdose crisis, with fentanyl and its analogs involved in more overdose deaths than any other illicit drug. Fentanyl is a synthethic opioid 50 to 100 times more potent than morphine. The drug is prescribed legally to treat severe pain, but illicit versions of fentanyl have flooded the black market.

Of growing concern to the DEA is the appearance of illegal pill press operations in the U.S. that are manufacturing millions of counterfeit painkillers and other medications, using fentanyl powder smuggled in from China and Mexico.

“Fentanyl will remain a serious threat to the United States as record numbers of individuals suffer fatal overdoses from illicit fentanyl sourced to foreign clandestine production,” the report warns.

“Clandestine fentanyl pill pressing operations will likely increase as DTOs (drug trafficking organizations) seek to appeal to the large pill abuser population in the United States, with counterfeit fentanyl-containing pills continuing to be associated with clusters of overdoses and deaths due to inconsistent mixing and often unexpectedly high potency.”

With China cracking down on illicit fentanyl laboratories, the DEA expects the primary source of fentanyl production to shift to Mexico and India.  

Fewest Prescription Opioids Since 2006

One bright spot in the DEA report is the continuing decline in overdoses involving prescription opioids. As PNN reported, overdose deaths involving natural and semisynthetic opioids, which include painkillers such as oxycodone and hydrocodone, were 3.8% lower in 2018 than in 2017.   

The DEA said the supply of prescription opioids is now at its lowest level since 2006. DEA production quotas for hydrocodone and oxycodone have been cut nearly in half since 2016, with further cuts proposed for 2020.

But while the retail supply of opioid medication has fallen dramatically, the diversion of opioids and other controlled drugs by medical professionals and wholesale distributors – so-called “lost in transit” diversion – has soared. There were 18,604 lost in transit reports filed in 2018, nearly six times the number reported in 2010.

“It is unclear if these dosage units are being diverted, destroyed, or truly lost. Although representative of only a small number of DEA registrants, diversion by physicians, nurses, and other medical professionals and their staff remains a threat to communities across the United States,” the report warns.

The DEA predicts “a steady decrease” in the supply of opioids over the next several years and that prescription drug abusers “may shift to abusing heroin, illicitly produced synthetic opioids, and methamphetamine to obtain similar effects, which may further increase overdose deaths through at least 2020.”

The DEA said the threat posed by psychostimulants such as methamphetamine and cocaine is “worsening and becoming more widespread.” While most cocaine users prefer to snort or inject the drugs, law enforcement agencies are starting to find cocaine in tablet or pill form.

“Whether these instances are harbingers of a new trend, an experiment, or simply the result of accidental contamination within poly-drug operations remains to be seen. Tableting and capsulizing cocaine may allow traffickers to capitalize on the considerably larger CPD user market with a different version of cocaine, further maximizing profits,” the DEA said.

Finally, while the DEA officially considers the herbal supplement kratom a “drug of concern” and once tried to ban it, there is once again no mention of kratom in its annual drug threat assessment.

Drug Overdose Deaths Fell 4% in 2018

By Pat Anson, PNN Editor

Drug overdose deaths in the United States dropped in 2018 for the first time in nearly three decades, according to a new CDC report that highlights the rapidly changing nature of the overdose crisis. While deaths linked to many prescription opioids declined, overdoses involving illicit fentanyl, cocaine and psychostimulants rose.

There were 67,367 drug overdose deaths in the U.S. in 2018, a 4.1% decline from 2017 when there were 70,237 fatal overdoses.

The rate of overdose deaths involving natural and semisynthetic opioids, which includes painkillers such as oxycodone and hydrocodone, was 3.8% lower. There were nearly 2,000 fewer deaths linked to painkillers in 2018 than there was the year before.

However, the decline in deaths involving opioid medication was more than offset by a continuing spike in overdoses linked to synthetic opioids other than methadone, which primarily involves illicit fentanyl and fentanyl analogs. The death rate in that category rose 9% from 2017 to 2018.

SOURCE: CDC

While the overall trend is encouraging, a top CDC official was cautious about preliminary data for drug deaths in 2019.

“One thing that we’re seeing is that the decline doesn’t appear to be continuing in 2019. It appears rather flat, maybe actually increasing a little bit,” said Robert Anderson, PhD, Chief of the Mortality Statistics Branch, National Center for Health Statistics.

“We do know that deaths due to synthetic opioids like fentanyl are continuing to increase into 2019 and we’re seeing increases similarly with cocaine and psychostimulants with abuse potential, the methamphetamine deaths."

Overdose deaths often involve multiple drugs, so a single death might be included in more than one category and be counted multiple times. A death that involved both fentanyl and cocaine, for example, would be classified by CDC researchers as an overdose involving both synthetic opioids and cocaine.

“There’s a lot of overlap between these categories and so a death may be actually counted in multiple categories, in two or more in many instances, making it difficult to partition the decline,” said Anderson. “We really don’t have a good handle on how best to do that.”  

Opioid Prescriptions Decline Significantly

A second CDC study on opioid prescribing shows that prescriptions have declined significantly in 11 states with prescription drug monitoring programs (PDMPs) that participate in the Prescription Behavior Surveillance System (PBSS). The 11 states include California, Ohio, Texas and Florida, and represent over a third of the U.S. population.

The decline in opioid prescriptions in the states ranged from 14.9% to 33% from 2010 to 2016, indicating that prescriptions were falling long before the CDC released its controversial opioid guideline in March, 2016. Significant declines were also noted in high dose opioid prescriptions, the average daily dose and in prescriptions obtained from multiple providers.

Despite the nearly decade-long decline in prescriptions, CDC researchers continue to blame opioid medication for the ongoing overdose crisis, offering little evidence to support that view.

“PDMP data collected by PBSS indicate that steady progress is being made in reducing the use and possible misuse of prescription-controlled substances in the United States. However, some persons who were misusing prescription opioids might have transitioned to heroin or illicitly manufactured fentanyl, a change that has made the drug overdose epidemic and associated overdose rates more complex,” researchers said.

“Because the opioid overdose epidemic began with increased deaths and treatment admissions related to opioid analgesics in the late 1990s, initiatives to address overprescribing might eventually result in fewer persons misusing either prescription or illicit drugs. Reduction in overprescribing opioids might lead ultimately to a decrease in overall overdose deaths.”

PDMP data for the CDC study came from the PBSS monitoring program at Brandeis University, where Dr. Andrew Kolodny is Co-Director of the Opioid Policy Research Collaborative. Kolodny is the founder and Executive Director of Physicians for Responsible Opioid Prescribing (PROP), an activist group that has long been critical of opioid prescribing.

FDA Approves Cocaine Nasal Spray

By Pat Anson, PNN Editor

FDA advisory committees have taken a dim view of opioid medications recently, soundly rejecting new drug applications for the “opioid of the future” oxycodegol and a new extended-release version of oxycodone.

There was also a split 13-13 vote on a relatively mild opioid painkiller – a combination of tramadol and the anti-inflammatory drug Celebrex..

Advisory committee recommendations are not binding on the FDA, but the votes reflect a growing reluctance to approve any new medication that may worsen the so-called opioid epidemic.

"We can't approve a drug in the midst of a public health crisis," said advisory committee member Steve Meisel, PharmD, who voted no on oxycodegol.

FDA advisors may be rejecting opioids out of hand, but cocaine is a different story. The agency this month quietly approved a nasal solution containing cocaine hydrochloride (HCI) for use as a local anesthetic. The nasal spray, made by the Lannet Company, is intended to relieve pain in mucous membranes during surgeries and procedures in the nasal cavities of adults.

"The FDA's approval of our Cocaine HCl product, the first NDA approval to include full clinical trials in the company's history, marks a major milestone in Lannett's 70+ years of operations," said Tim Crew, chief executive officer of Lannett in a news release.

"We believe the product has the potential to be an excellent option for the labeled indication. We expect to launch the product shortly, under the brand name Numbrino."

Numb-rino. Get it?

While cocaine is well-known as a drug of abuse, it is classified by the DEA as a Schedule II controlled substance, alongside hydrocodone and oxycodone. Cocaine’s use in medicine is not unheard of. It was commonly used as an alternative to morphine in the last half of the 19th Century until it fell out favor because of high rates of addiction.

Numbrino is not the first nasal spray containing cocaine to be approved by the FDA. In 2017, the agency approved the nasal solution Goprelto, which is also intended for use during surgeries and procedures in nasal cavities. 

Nevertheless, the FDA’s approval of a drug containing cocaine was so unusual that Snopes conducted a fact check to see if it was true. An FDA spokesperson confirmed to Snopes that Numbrino was approved, along with warning labels and other safeguards to discourage its abuse.

“Cocaine hydrochloride nasal solution contains cocaine, a Schedule II substance with a high potential for abuse. However, when used according to the directions provided in the labeling, physical dependence and withdrawal symptoms are unlikely to develop because this drug is for single use during diagnostic procedures and surgeries,” the FDA said.

“To minimize these risks, the labeling suggests that health care facilities using the drug implement effective accounting procedures, in addition to routine procedures for handling controlled substances. Notably, this will be used as an anesthetic by trained health care professionals during diagnostic procedures and surgeries, not by patients directly. It is not available by prescription.”

Numbrino was approved without any of the controversy that surrounds opioid painkillers. In 2018, the FDA’s approval of Dsuvia — a single use opioid intended for severely wounded soldiers and trauma patients — was panned by critics, who called the drug a “dangerously unnecessary opioid medication." Like Numbrino, Dsuvia is not available by prescription and can only be administered by a healthcare professional.

Alcohol Deaths Double in U.S.

By Pat Anson, PNN Editor

Alcohol related deaths in the U.S. have doubled in the past two decades, according to a new study that highlights an under-reported aspect of the overdose crisis: while deaths involving prescription opioids are declining, alcohol abuse appears to be increasing.

Researchers at the National Institute on Alcohol Abuse and Alcoholism (NIAAA) found the number of death certificates mentioning alcohol more than doubled from 35,914 in 1999 to 72,558 in 2017.

By comparison, 17,029 deaths in 2017 involved a prescription opioid, according to CDC estimates.

“The current findings suggest that alcohol-related deaths involving injuries, overdoses and chronic diseases are increasing across a wide swath of the population. The report is a wakeup call to the growing threat alcohol poses to public health,” said NIAAA Director Dr. George Koob.

Nearly 1 million alcohol-related deaths were recorded between 1999-2017. About half the deaths resulted from chronic liver disease or overdoses on alcohol alone or with other drugs.

Researchers noted that alcohol-related deaths were increasing among people in almost every age, race and ethnic group. Their study is published in Alcoholism: Clinical & Experimental Research.

“Taken together, the findings of this study and others suggests that alcohol-related harms are increasing at multiple levels – from ED visits and hospitalizations to deaths. We know that the contribution of alcohol often fails to make it onto death certificates. Better surveillance of alcohol involvement in mortality is essential in order to better understand and address the impact of alcohol on public health,” said Koob.

Other drugs besides alcohol are increasingly involved in overdoses. A recent analysis of over one million urine drug tests conducted by Millennium Health found that positive results for illicit fentanyl rose by 333% since 2013, while positive rates for methamphetamine increased by 486 percent.

That study, published in JAMA Network Open, found that positive rates for heroin and cocaine peaked in 2016 and appear to be declining.

The analysis is similar to a 2019 report from the National Institute on Drug Abuse, which found that drug deaths involving prescription opioids and heroin have plateaued, while overdoses involving methamphetamine, cocaine and benzodiazepines have risen sharply.

Unreliable Data

Just how reliable is the federal data on drug use and overdoses? Not very, according to another study published in Drug and Alcohol Dependence.

Troy Quast, PhD, an associate professor at the University of Florida’s College of Public Health, compared overdose data from the Florida Medical Examiners Commission (FMEC) to drug deaths in a CDC database. Quast found the federal data significantly undercounted overdose deaths in Florida linked to cocaine, benzodiazepines, amphetamines and other drugs.

Florida medical examiners are required by law to wait for complete toxicology results before submitting an official cause of death to FMEC. It often takes weeks or months to identify the exact drug or drugs that cause an overdose. By contrast, the CDC data is based on death certificates filed by coroners and other local authorities, which often don't include detailed toxicology reports. This causes significant differences between the two databases.

Between 2003 and 2017, roughly one-in-three overdose deaths in Florida involving illicit or prescription opioids were not reported by the federal government. The discrepancy wasn’t limited to opioids. Quast also found that nearly 3,000 deaths in Florida caused by cocaine were not included in the CDC database. Overdose deaths involving benzodiazepines and amphetamines were also significantly under-reported.

"The CDC data are widely reported in the news and referenced by politicians, which is problematic since those estimates significantly undercount the true scope of the epidemic for specific drugs," said Quast. "The rate of under-reporting for all overdose deaths in Florida is near the national average, so the problem is not to the state."

This isn’t the first time the reliability of CDC data has been questioned. In 2018, CDC researchers admitted that many overdoses involving illicit fentanyl and other synthetic black market opioids were erroneously counted as prescription drug deaths. As result, federal estimates prior to 2017 "significantly inflate estimates" of prescription opioid deaths.

Even the adjusted estimates are imprecise, because the number of deaths involving diverted prescriptions or counterfeit drugs is unknown and drugs are not identified on 20% of death certificates. When the drugs are listed, many overdoses are counted multiple times by the government because more than one substance is involved.

The federal government is working to improve the collection of overdose data. Over 30 states are now enrolled in the CDC's Enhanced State Opioid Overdose Surveillance program, which seeks to improve overdose data by including toxicology reports and hospital billing records.

In 2017, the program reported that nearly 59 percent of overdose deaths involved illicit opioids like fentanyl and heroin, while 18.5% had both illicit and prescription opioids. Less than 18% tested positive for prescription opioids only.

A recent study of drug deaths in Massachusetts found that only 1.3% of overdose victims who died from an opioid painkiller had an active prescription for the drug – meaning the medication was probably diverted, stolen or bought on the street.  

Prescription Opioids Play Minor Role in Massachusetts Overdoses

By Pat Anson, PNN Editor

Two new studies in Massachusetts – one of the states hardest hit by the overdose crisis – highlight the role of multiple substances in most overdose deaths and how limiting the supply of prescription opioids has failed to reduce the number of drug deaths.

Researchers at Boston Medical Center's Grayken Center for Addiction analyzed toxicology reports on nearly 2,250 fatal overdoses involving opioids in Massachusetts between 2014 and 2015. Overdose data in Massachusetts is considered more reliable because it is one of the few states to extensively use toxicology testing.

Only 9 percent of the deaths in Massachusetts involved prescription opioids alone. Most of the overdoses (72%) involved illicit fentanyl or heroin, while one in five (19%) involved a combination of heroin, fentanyl or prescription opioids.

Other substances such as alcohol, marijuana, stimulants (cocaine and methamphetamine) and non-opioid medications (benzodiazepines and gabapentin) were also frequently involved.

“Using multiple substances, in addition to opioids, is the rule rather than the exception for opioid-related deaths,” researchers reported in the journal Drug and Alcohol Dependence.

“Our study draws attention to the heterogeneity of the problem at hand and that there is not a one-size-fits-all approach to addressing the overdose epidemic, which is increasingly driven by polysubstance use.”

Over half of the Massachusetts overdoses involved someone with a diagnosed mental illness. Homelessness and a recent incarceration also raised the risk of a fatal overdose involving both opioids and stimulants.

"As a provider, these findings indicate a pressing need to address and treat not just opioid use disorder, but other substances that patients are misusing," said lead author Joshua Barocas, MD, an infectious disease physician at BMC. "To truly make a difference in reducing opioid overdose deaths, we must tackle issues such as homelessness and access to mental health services. This means not only investing in treatment but also implementing tailored programs that address the specific barriers to accessing care."

Opioid Prescriptions Down 39% since 2015

The number of opioid prescriptions has declined significantly in Massachusetts over the last four years, according to a recent report from the state’s Department of Public Health. In the first quarter of 2019 there were over 518,000 prescriptions filled for Schedule II opioids such as hydrocodone and oxycodone – a 39% decline from the first quarter of 2015.

But the decrease in prescriptions has failed to make much of a dent in Massachusetts’ opioid overdose rate, which peaked in 2016 with 2,100 deaths and remains stubbornly high.

In 2018, nearly nine out of ten opioid-related deaths (89%) in the state involved illicit fentanyl, with cocaine (39%), heroin (32%), and benzodiazepines (40%) such as Xanax also commonly found.

Only about ten percent of the overdose deaths in the fourth quarter of 2018 involved prescriptions opioids, virtually unchanged from the 2014-2015 study.

90% of Massachusetts Overdoses Linked to Fentanyl

By Pat Anson, Editor

Nearly 90 percent of opioid-related overdose deaths in Massachusetts now involve fentanyl, according to a new report that documents the rapidly changing nature of the opioid crisis. Less than 20 percent of drug overdoses in the state were linked to prescription opioids.

In the second quarter of 2018, Massachusetts health officials say 498 people died from an opioid-related overdose – the third straight quarter that opioid deaths have declined.

But the good news was tempered by the rising toll taken by fentanyl -- the synthetic opioid that’s become a deadly scourge on the black market. Fentanyl is often mixed with heroin, cocaine and counterfeit drugs to increase their potency. 

Because Massachusetts was one of the first states to conduct blood toxicology tests in overdose cases, it’s quarterly reports on drug deaths are considered more accurate than federal estimates and more likely to spot emerging trends in drug use. 

"This quarterly report provides a new level of data revealing an unsettling correlation between high levels of synthetic fentanyl present in toxicology reports and overdose death rates. It is critically important that the Commonwealth understand and study this information so we can better respond to this disease and help more people,” Massachusetts Gov. Charlie Baker said in a statement.

Another trend documented in Massachusetts is the increasing role played by cocaine and benzodiazepines --- an anti-anxiety medication – in drug overdoses. In the first quarter of 2018, cocaine (43%) and benzodiazepines (42%) were involved in more overdoses than heroin (34%) and prescription opioids (19%).

Drug experts say many cocaine users may not realize their drug has been spiked with fentanyl, while many people who buy Xanax or Valium on the black market don’t know they’re getting counterfeit medication laced with fentanyl.

“If you are using illicit drugs in Massachusetts, you really have to be aware that fentanyl is a risk no matter which drug you’re using,” Dr. Monica Bharel, Massachusetts public health commissioner told The Boston Globe. “The increased risk of death related to fentanyl is what’s driving this epidemic.”

Fentanyl is also involved in a growing number of fatal overdoses in Pennsylvania. According to the Drug Enforcement Administration, there were 5,456 overdose deaths in Pennsylvania last year. Of those, over 67% percent involved fentanyl. The presence of fentanyl or its chemical cousins in overdose deaths rose almost 400% in the state from 2015 to 2017.

Most overdoses involve multiple drugs and blood tests alone do not determine a cause of death -- only which drugs were present at the time of death.

CDC Blames Fentanyl for Spike in Overdose Deaths

By Pat Anson, Editor

The Centers for Disease Control and Prevention released a new report today estimating that 63,632 Americans died of a drug overdose in 2016 – a 21.5% increase over the 2015 total.  

The sharp rise in drug deaths is blamed largely on illicit fentanyl, a powerful synthetic opioid that has become a scourge on the black market. Deaths involving synthetic opioids doubled in 2016, accounting for about a third of all drug overdoses and nearly half of all opioid-related deaths.

For their latest report, CDC researchers used a new “conservative definition” to count opioid deaths – one that more accurately reflects the number of deaths involving prescription opioids by excluding those attributed to fentanyl and other synthetic opioids. Over 17,000 deaths were attributed to prescription opioids in 2016, about half the number that would have been counted under the “traditional definition” used in previous reports.

CDC researchers recently acknowledged that the old method "significantly inflate estimates" of prescription opioid deaths.

The new report, based on surveillance data from 31 states and the District of Columbia, shows overdose deaths increasing for both men and women and across all races and demographics.  A wider variety of drugs are also implicated:

• Fentanyl and synthetic opioid deaths rose 100%
• Cocaine deaths rose 52.4%
• Psychostimulant deaths rose 33.3%
• Heroin deaths rose 19.5%
• Prescription opioid deaths rose 10.6%

The CDC also acknowledged that illicit fentanyl is often mixed into counterfeit opioid and benzodiazepine pills, heroin and cocaine, likely contributing to overdoses attributed to those substances.

2016 DRUG RELATED DEATHS

West Virginia led the nation with the highest opioid overdose rate (43.4 deaths for every 100,000 residents), followed by New Hampshire, Ohio, Washington DC, Maryland and Massachusetts.  Texas has the lowest opioid overdose rate.

‘Inaccurate and Misleading” Overdose Data

The CDC's new method of classifying opioid deaths still needs improvement, according to John Lilly, DO, a family physician in Missouri who took a hard look at the government’s overdose numbers. Lilly estimates that 16,809 Americans died from an overdose of prescription opioids in 2016.

“Not all opioids are identical in abuse potential and likely lethality, yet government statistics group causes of death in a way that obscures the importance of identifying specific agents involved in deadly overdoses,” Lilly wrote in a peer reviewed article recently published in the Journal of American Physicians and Surgeons..

Lilly faults the National Institute on Drug Abuse (NIDA) -- which relies on a CDC database -- for using “inaccurate and misleading” death certificate codes to classify drug deaths. In its report for 2016, NIDA counted illicit fentanyl overdoses as deaths involving prescription opioids. As a result, deaths attributed to pain medication rose by 43 percent, at a time when the number of opioid prescriptions actually declined.

“That large an increase in one year from legal prescriptions does not make sense, particularly as these were being strongly discouraged,” Lilly wrote. “Rather than legal prescription drugs, illicit fentanyl is rapidly increasing and becoming the opioid of choice for those who misuse opioids... Targeting legal prescriptions is thus unlikely to reduce overdose deaths, but it may increase them by driving more users to illegal sources.”

Some researchers believe the government undercounts the number of opioid related deaths by as much as 35 percent because the actual cause of death isn’t listed on many death certificates.

“We have a real crisis, and one of the things we need to invest in, if we’re going to make progress, is getting better information,” said Christopher Ruhm, PhD, a professor at the University of Virginia and the author of a overdose study recently published in the journal Addiction.

Ruhm told Kaiser Health News the real number of opioid related deaths is probably closer to 50,000.

Lower Back Pain Linked to More Drug Use

By Pat Anson, Editor

People with chronic lower back pain are more likely to have used illicit drugs -- including marijuana, cocaine, heroin and methamphetamine -- compared to those without back pain, according to new research published in the journal Spine.

The study also found that people with lower back pain who had used illicit drugs were somewhat more likely to have an active prescription for opioid pain medication (22.5% vs. 15%).

Lower back pain is the world’s leading cause of disability and most people will suffer from it at least once in their lives. Although nearly a quarter of the opioid prescriptions written in the U.S. are for low back pain, medical guidelines often recommend against it.

Researchers analyzed data from over 5,000 U.S. adults who participated in a nationally representative health study and found that nearly half (49%) of those who reported lower back pain admitted having a history of illicit drug use, compared to 43% of those without back pain.

Current use of illicit drugs (within the past 30 days) was much lower in both groups; 14% versus nine percent.

The study did not differentiate between recreational and medical marijuana use, nor did it draw a distinction between marijuana use in states where it is legal and where it is not. All marijuana use was considered "illicit."

All four illicit drugs in the survey were more commonly used by people with low back pain compared to those without back pain. Rates of lifetime use were 46.5% versus 42% for marijuana; 22% vs. 14% for cocaine; 9% vs. 5% for methamphetamine; and 5% vs. 2% for heroin.

Researchers said there was no evidence that illicit drug use causes lower back pain, only that there was an association between the two that bears watching when opioids are prescribed.

“The association between a history of illicit drug use and prescription opioid use in the cLBP (chronic lower back pain) population is consistent with previous studies, but may be confounded by other clinical conditions,” said lead author Anna Shmagel, MD, Division of Rheumatic and Autoimmune Diseases at the University of Minnesota.

“Mental health disorders, for example, have been associated with both illicit substance use and prescription opioid use in the chronic low back pain population. In the context of management, however, illicit drug abuse is predictive of aberrant prescription opioid behaviors. As we face a prescription opioid addiction epidemic, careful assessment of illicit drug use history may aid prescribing decisions.”

In a recent analysis of prescriptions filled for 12 million of its members, pharmacy benefit manager Prime Therapeutics found that nearly a quarter of the opioid prescriptions were written to treat low back pain.

"Our analysis found low back pain was the most common diagnosis among all members taking an opioid, even though medical guidelines suggest the risks are likely greater than the benefits for these individuals," said Catherine Starner, PharmD, lead health researcher for Prime Therapeutics.

In a 2014 position paper, the American Academy of Neurology said opioids provide “significant short term pain relief” for low back pain, but there was “no substantial evidence” that long term use outweighs the risk of addiction and overdose.
