New research published in the Journal of the American Medical Association (JAMA) provides compelling evidence that legal cannabis access may help address the ongoing opioid crisis.

Key Findings

The study analyzed data from 2010-2023 across all 50 states and found that states with medical cannabis programs saw a 20% reduction in opioid prescriptions and a 25% decrease in opioid-related overdose deaths.

Substitution Effect

Implications for Policy

The findings add to growing evidence supporting cannabis as a harm reduction tool and may influence future policy decisions regarding medical marijuana programs.
