We study the effect of state medical marijuana laws (MMLs) on workers' compensation (WC) claiming among adults. Medical marijuana is plausibly related to WC claiming by allowing improved symptom management, and thus reduced need for the benefit, among injured or ill workers. We use data on claiming drawn from the Annual Social and Economic supplement to the Current Population Survey over the period 1989 to 2012, coupled with a differences-in-differences design to provide the first evidence on this relationship. Our estimates show that, post MML, WC claiming declines, both the propensity to claim and the level of income from WC. These findings suggest that medical marijuana can allow workers to better manage symptoms associated with workplace injuries and illnesses and, in turn, reduce need for WC. However, the reductions in WC claiming post MML are very modest in size.
我们研究了州医用大麻法（MML）对成年人工伤保险（WC）索赔的影响。医用大麻通过允许受伤或患病的工人更好地控制症状，从而减少对福利的需求，这与 WC 索赔之间存在明显的关系。我们使用了 1989 年至 2012 年期间从“当前人口调查”年度社会经济补充数据中提取的索赔数据，并结合差异中的差异设计，首次提供了这方面关系的证据。我们的估计表明，在 MML 之后，WC 索赔减少，包括索赔的倾向和 WC 收入的水平。这些发现表明，医用大麻可以使工人更好地控制与工作场所受伤和疾病相关的症状，从而减少对 WC 的需求。然而，MML 后 WC 索赔的减少幅度非常小。
