Legal cannabis linked to higher disorder rates in seniors

This study analyzed Medicare claims data from 2010-2022 to examine how recreational cannabis legalization affects cannabis-related disorders (CRDs) in older adults across the United States. Researchers compared health outcomes in states that passed recreational cannabis laws and opened dispensaries against states without legalization, using statistical models to isolate the effects of legalization. The findings reveal concerning trends: following legalization, CRD diagnoses increased by 19.73 cases per 10,000 Medicare enrollees, and healthcare claims involving CRDs jumped 20.56 per 10,000 enrollees. Similarly, when recreational dispensaries actually opened, cases rose 14.14 per 10,000 enrollees with 13.98 additional claims per 10,000.

The research suggests that increased access to cannabis through legal dispensaries correlates with higher rates of cannabis-related disorders among seniors, which may include conditions like cannabis use disorder, dependence, and acute health complications. While the study doesn't prove legalization directly caused these increases, the timing and statistical significance suggest a strong association. The implications are particularly important for older adults, who may face unique risks from cannabis use including interactions with medications, cognitive effects, and falls. The authors emphasize that policymakers considering cannabis legalization should weigh these potential harms against other benefits, particularly regarding vulnerable populations like the elderly who already face complex health management challenges.
