Yet another study finds link between marijuana reform and a reduction in opioid deaths

Ajph-logoThe evidence suggesting that marijuana reform could and should be a part of the toolbox of responses to the opioid crisis is starting to become overwhelming.  I make that statement as a result of this latest study published in the American Journal of Public Health under the title "Recreational Cannabis Legalization and Opioid-Related Deaths in Colorado, 2000–2015." Here is the article's abstract:

Objectives.

To examine the association between Colorado’s legalization of recreational cannabis use and opioid-related deaths.

Methods.

We used an interrupted time-series design (2000–2015) to compare changes in level and slope of monthly opioid-related deaths before and after Colorado stores began selling recreational cannabis. We also describe the percent change in opioid-related deaths by comparing the unadjusted model-smoothed number of deaths at the end of follow-up with the number of deaths just prior to legalization.

Results.

Colorado’s legalization of recreational cannabis sales and use resulted in a 0.7 deaths per month (b = −0.68; 95% confidence interval = −1.34, −0.03) reduction in opioid-related deaths. This reduction represents a reversal of the upward trend in opioid-related deaths in Colorado.

Conclusions.

Legalization of cannabis in Colorado was associated with short-term reductions in opioid-related deaths. As additional data become available, research should replicate these analyses in other states with legal recreational cannabis.
