Does Marijuana Legalization Affect Work Capacity? Evidence from Workers’ Compensation Benefits

We study the effect of state recreational marijuana laws (RMLs) on workers’ compensation (WC) benefit receipt among adults 40-62 years. We find that WC receipt declines in response to RML adoption both in terms of the propensity to receive benefits and benefit amount. We estimate complementary declines in non-traumatic workplace injury rates and the incidence of work-limiting disabilities. We offer evidence that the primary driver of these reductions is an improvement in work capacity, likely due to access to an additional form of pain management therapy.
