Limiting initial prescriptions for opioid pain medication to 5-days’ supply did not reduce the rate at which patients in New Jersey transitioned to long-term opioid use, according to a new study at Rutgers University.

In 2017, New Jersey became one of the first states in the country to impose a mandatory 5-day limit on initial opioid prescriptions for acute pain. If a patient needed more, their doctor would have to write a new prescription, enroll them in a pain management program, and counsel them on the risks of opioid addiction.

At least 38 other states adopted similar laws, with the goal of reducing opioid diversion, misuse and overdose. Six years later, there is little evidence that New Jersey’s 5-day limit saved lives or accomplished any of its goals.

“This policy’s apparent failure to achieve its goals illustrates the extreme difficulty of solving healthcare problems by dictating physician behavior,” said senior author Stephen Crystal, PhD, director of the Rutgers Center for Health Services Research.

Crystal and his colleagues analyzed pharmacy data for over 130,000 New Jersey Medicaid patients who were prescribed opioids for the first time between 2014 to 2019. Their findings, recently published in the Journal of General Internal Medicine, show that new opioid prescriptions fell at a monthly rate of less than one percent (0.76%) after the 5-day limit was imposed, a decline that was about half the monthly rate (1.62%) prescriptions were falling before the limit took effect.

Doctors were writing fewer prescriptions for opioids in New Jersey and other states long before limits on the supply were even passed. Opioid prescriptions nationally are now at their lowest level in over 20 years.

“Opioid prescribing was already decreasing before this policy went into effect,” said lead author Peter Treitler, a research project manager at the Rutgers Institute for Health, Health Care Policy and Aging Research. “And so, by the time this New Jersey policy went into effect, it really didn’t change prescribing practices very much, at least in the New Jersey Medicaid population.”

An earlier study by the Rutgers research team found that medically treated overdoses in the Medicaid population tripled in New Jersey after the 5-day limit was imposed. Most of the overdoses involved illicit fentanyl and other street drugs, not prescription opioids.

Less than a third of New Jersey’s overdose survivors were even diagnosed with a chronic pain condition, suggesting the state’s focus on limiting pain medication was misdirected. Most people who overdose suffer from substance abuse disorder, depression or other mental health issues. And most overdoses involve illicit fentanyl and other street drugs, not prescribed medication.

In 2022, there were nearly 2,900 drug deaths in New Jersey – about 30% more than the number that overdosed in 2016, the year before the state’s 5-day limit became law.
