Legalizing Marijuana May End the Opioid Crisis, Say Scientists

A new study shows how access to medical marijuana significantly impacted the use of opioids by patients.

As we reported previously, scientists from the University of New Mexico have been studying how access to marijuana may help alleviate the opioid crisis, declared a national emergency by President Trump. Their study has now been published in the journal PLOS One, with the researchers concluding that there is “clinically and statistically significant evidence” that increased cannabis use led to patients cutting down on opioids and improved their quality of life.

The study analyzed the health data of 66 patients who were using opioids habitually to manage their severe chronic pain. 37 of the patients were enrolled in a medical marijuana program between 2010 and 2015 while 29 patients in the control group were not.

The scientists found that patients using cannabis were 17 times more likely to stop their prescribed opioids and five times more likely to lower their daily dosage of opioids. On average, they cut their doses in half. Comparatively, the patients not enrolled in the medical marijuana program actually increased their opioid usage by more than 10%.

The cannabis use also had a positive effect on the life of the patients overall, with most reporting improved levels of activity, social life and concentration. None of the patients in the program reported adverse effects.

Overall, over 40% of medical cannabis patients stopped filling their opioid prescriptions completely after about a year and a half of being in the program. This result indicates that medical marijuana can be used as an effective alternative to opioids, say the scientists, especially in light of the statistics that over 90 people die from opioids every day in the U.S.

“If cannabis can serve as an alternative to prescription opioids for at least some patients, legislators and the medical community may want to consider medical cannabis programs as a potential tool for combating the current opioid epidemic,” wrote the scientists.

The researchers stress that their findings are preliminary and further studies are necessary, with larger samples.
