This paper investigates the causal relationship between cannabis consumption and mental health using state-level longitudinal data in the United States from 2005-2018. We first estimate the impact of cannabis legalization on cannabis consumption and mental health among the states that have legalized cannabis using recent developments in the difference-in-differences literature to account for treatment heterogeneity across cohorts and time under staggered treatment adoption. We then estimate the direct effect of cannabis consumption on mental health using an instrumented difference-in-differences (DDIV) approach exploiting state-level variation in the legal status of cannabis. We link the legalization of cannabis to an average increase of 1.59 percentage points (7.3 percent) and 0.92 percentage points (5.0 percent) in the proportion of the population with symptoms of a mental health disorder for adults aged 18- 25 and aged 26+, respectively. Our DDIV estimates suggest that, among the states that have legalized cannabis, roughly 2 out of 10 adults that engage in frequent cannabis consumption developed symptoms of a mental health disorder.
