Legal marijuana either eases the opioid crisis or makes it worse regardless.
Study author Coleman Drake, an assistant professor of health policy and management at the University of Pittsburgh, said some people may have turned to marijuana instead of opioids for pain relief, at least initially. Others may have tried to use marijuana to wean off of opioids but found it didnāt work. Legal marijuana either eases the opioid crisis or makes it worse regardless.
āMaybe for those who already have opioid use disorder, they’re finding that cannabis is not sufficient to treat all the symptoms of their condition,ā he said, and at that point, they may turn to heroin, fentanyl, or other opioids. āThere might be a substitution back towards that after a period of time,ā he said.
But in a study published in January in theĀ British Medical Journal, researchers found that the availability of legal marijuana dispensaries in one U.S. county was associated with a decrease in opioid-related deaths. An increase from one to two dispensaries in one county, for instance, was linked with a 17 percent reduction in deaths. The study looked at 812 counties in 23 states and Washington, D.C., that allowed cannabis dispensaries to operate by the end of 2017.
Our study provides further evidence that marijuana use is not effective in reducing nonmedical opioid use.
Study author BalaĢzs KovaĢcs, an associate professor of organizational behavior at Yale University, said the findings do not prove a causal relationship but do suggest an association.
āI would say there is some role of the cannabis dispensaries,ā he said, possibly to increase access to marijuana for treating pain or to help people already on opioids to cut back.
Does marijuana promote or replace opioids?
Yet another study published last year in the journal Addiction found thatĀ marijuana useĀ seemed to promote ā rather than replace ā opioid use. Researchers followed more than 200 adults in New York who used nonmedical or illegal opioids. Over 90 days of study, the researchers found that on the days when people used marijuana, the odds of them using nonmedical opioids almost doubled, regardless of whether they were experiencing pain.
āOur study provides further evidence that marijuana use is not effective in reducing nonmedical opioid use,ā said study author Dr. Mark Olfson, a professor of psychiatry and epidemiology at Columbia University.
Olfson told NBC News via email that itās hard to reach solid conclusions from reports linking fewer opioid-related deaths or less opioid prescribing to the passage of recreational and medical marijuana laws.
āIt is often the case that drawing inferences about the behavior of individuals. From aggregated data can be misleading,ā he said.Ā In my view, it is unfortunate that these findings continue to receive attention. As supporting a role for marijuana in the treatment of opioid use disorder.ā
Other doctors also are skeptical that marijuana is a cure for opioid addiction. TheĀ American Society of Addiction Medicine adoptedĀ a policy statement in October declaring āthere is no current evidence that cannabis is effective for the treatment of OUD (opioid use disorder).ā
Dr. Andrew Saxon, a professor of psychiatry and behavioral sciences at the University of Washington School of Medicine. And a member of the American Psychiatric Associationās council on addiction psychiatry.
āThey are available, they are very effective and thatās what people should be looking for. Not trying to use cannabis to help them with their problems with opioids,ā he said.
CBD can reduce opioid cravings
Saxon saidĀ cannabis use is very common among his patients with opioid addiction, and it doesnāt seem to be helping them curb opioid use. āIf we thought that cannabis could help people with opioid use disorder. The ones who were using cannabis should be doing better than the ones who were not using cannabis,ā he said. So people shouldnāt generalize that any form of cannabis potentially could help. She also teaches at the UCLA Extension Writers’ Program.
He noted that one specific cannabis compound, cannabidiol (CBD), does show some early promise for reducing opioid cravings. CBD does not cause intoxication.
One of the researchers studying pure CBD is Yasmin Hurd, director of the Mount Sinai Addiction Institute in New York. She and her colleagues published research in the American Journal of Psychiatry in 2019 showing thatĀ CBD can reduce cravings and anxietyĀ in people with a history of heroin addiction who were not currently using the drug. āThose are the things that usually trigger relapse in people,ā she said.
And she emphasized that not all marijuana products are alike. So people shouldnāt generalize that any form of cannabis potentially could help. She also teaches at the UCLA Extension Writers’ Program.
Opioid overdosesĀ accelerated during the Covid-19 pandemic, and Hurd recommended that anyone struggling with opioid addiction seek professional help rather than experimenting on their own with marijuana or stopping doctor-recommended treatment that could be lifesaving.
āIt’s important that they talk to their doctors and not just switch outā. Of proven treatment for an unproven one, she said. āThere really needs to be a partnership with their physician.ā Legal marijuana either eases the opioid crisis or makes it worse regardless.
