Opioid Deaths Fall When Cannabis Stores Rise, Analysis SuggestsPosted by On


Access to legal cannabis stores was linked with fewer opioid deaths in the U.S., a new analysis suggested.

The number of marijuana dispensaries in a county was negatively related to log-transformed opioid mortality rate, adjusted for age (β -0.17, 95% CI -0.23 to -0.11), reported Balázs Kovács, PhD, of Yale University School of Management in New Haven, Connecticut, and Greta Hsu, PhD, of University of California Davis Graduate School of Management.

This means that increasing the number of storefront dispensaries from one to two was tied to a 17% reduction in death rates of all opioid types, and an increase from two to three stores was associated with a further 8.5% reduction in mortality, Kovács and Hsu noted.

The relationship was stronger — leading to an estimated 21% drop in mortality — when only deaths from synthetic non-methadone opioids like fentanyl were considered (β -0.21, 95% CI -0.27 to -0.14), they wrote in The BMJ.

“We find this relationship holds for both medical dispensaries, which serve only patients who have a state-approved medical card or doctor’s recommendation, as well as for recreational dispensaries, which sell to adults 21 years and older,” Kovács said.

As business school researchers, Kovács and Hsu first became interested in the increasing prevalence of legal cannabis stores as an organizational issue.
