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.
