The Federal Government Should Consider Medical Marijuana a Potential Ally in the Fight Against Opioid Addiction

The United States is in the midst of what many are calling an opioid epidemic. According to the American Society of Addiction Medicine, more than 1.9 million people in the U.S. have a substance use disorders involving prescription pain medications, and another 580,000 have substance abuse issues with heroin. The human costs of these rates of addiction are staggering.   Of the approximately 50,000 lethal drug overdoses that happen each year, almost 20,000 are the result of prescription opioids, and another 10,000 are the result of heroin. While prescription painkillers traditionally aren’t as dangerous as heroin, the connection between the two is well established. According to a 2013 survey, about 80% of heroin users started out abusing opioid painkillers.

Despite continued efforts at nearly every level of government, the rates of opioid addiction and overdose have continued to climb. However, researchers have identified an unlikely ally that may have quietly been slowing the rise of opioid use in certain states: medical marijuana.

study recently released by Columbia University’s Mailman School of Public Health suggests that medical marijuana availability is linked to decreases in opioid usage. The study looked at opioid prevalence in autopsy reports from fatal car accidents over 14 years, and found that states that passed medical marijuana laws in that period saw a relative decrease in opioid prevalence compared to states that didn’t. While this study is making a splash, it’s just the most recent piece in a long line of research into the connection between medical marijuana availability and opioid use. One study published in Health Affairs in July showed that states which implemented medical marijuana laws between 2010-2013 saw a significant decrease in Medicare Part D prescriptions filled for medications for which marijuana is a possible alternative therapy — including opioids. Another study from 2014 showed a 25% decrease in deaths from prescription pain medication overdoses in states that implemented medical marijuana laws.

Unfortunately, as these medical marijuana success stories roll in, the federal government has been characteristically slow to adapt. While many were hopeful that the Drug Enforcement Agency (DEA) would reclassify marijuana as a Schedule II drug — opening up the possibility for more research and for medical availability in all 50 states — the DEA confirmed in August that it would be maintaining its Schedule I classification for marijuana. This means marijuana will remain classified with the most dangerous drugs including heroin, ecstasy, and MDMA — subject to more stringent regulation than cocaine, which is a Schedule II drug.

Whether or not one supports full marijuana legalization, the evidence for the positive effects of medical marijuana in combating the opioid crisis is at the point where the federal government should start taking it seriously.  The DEA’s position is that the science to support marijuana as a medical therapy isn’t yet sufficient to warrant reclassification, pointing to the fact that the FDA has not yet authorized its use for medical purposes, which is understandable. But it’s not clear that argument withstands a cost-benefit analysis in light of recent research. As previously noted, states that implement medical marijuana laws see a decrease of 25% in prescription pain medication overdose fatalities. Given that the U.S. has about 30,000 overdose deaths a year from heroin and prescription opioids, every year the federal government waits to seriously consider nation-wide medical marijuana potentially raises the opioid fatality count by 7,500. So while the instinct to wait for more research is understandable — and one that I would support in many contexts — waiting is not a costless decision.

It’s also not clear there is much to be gained by waiting on the FDA. To get through the FDA approval process, medical marijuana would potentially go through clinical trials, but those only require the drug be tested on about 1000 people for a limited time. This makes a lot of sense as a barrier to market entry for brand new chemical compounds that have previously only been administered to animals, but it’s unclear that it would add significant insight in the context of medical marijuana — a substance used by an estimated 22 million Americans in 2014.

The opioid epidemic isn’t going anywhere any time soon, and the impact it’s having on our communities is absolutely devastating. Despite years of public attention and many initiatives at every level of government, there has yet to be a solution implemented to effectively combat opioid addiction on a national scale. Congress passed an attempt at a solution over the summer, but only allocated about half of the requested funds to the endeavor, which doesn’t bode well for its long-term chances of success. It’s time to think outside the box. The substantial costs of inaction and the possible benefits of medical marijuana are such that its potential should no longer be ignored. Helping to pave the way for medical marijuana across the country is not something the federal government should do lightly — but neither is failing to recognize an ally in the fight against the opioid epidemic as its death toll continues to rise.

  1. Cannabis Twenty-Four Seven was created to spread information about the wonderful cannabis plant.
    We aim to impart information about marijuana and all the other benefits of products derived from it like CBD oil.
    The site alzo shares as much information that it can that may be beneficial for cannabis growers and cannabis users alike.
    Marijuana has long been demonized but if you think about it, marijuana is a plant that is
    a gift from Mother Nature. It wass created so we humans can benefit from it.

    The cannabis plant is not only useful for its medicinal properties,
    but it also has otfher industrial uses. With that
    said, the industriial use of marijuana is good
    for the environment as it has a very low carbon footprint.
    Too bad, more research cannot be conducted about it because this plant has been deemed “illegal” by the powers that control
    this world. Marijuana should not be prohibited nor regulated by man-made statutes.
    The state that the world is in right now regarding cannabis is one that is in contrast with natural law.

    Man labeling cannabis as illergal is like saying that man knows
    more about creation than Mother Nature. It iis a shame, really.
