We study the effect of state medical marijuana laws on labor supply among older adults; the demographic group with the highest rates of many health conditions for which marijuana may be an effective treatment. We use the Health and Retirement Study to study this question and estimate differences-in-differences regression models. We find that passage of a state medical marijuana law leads to increases in labor supply among older adults. These effects should be considered as policymakers determine how best to regulate access to medical marijuana.
