摘要
We use retail scanner data on purchases of alcoholic beverages across US counties for 2006 to 2015 to study the link between medical marijuana laws (MMLs) and alcohol consumption. To do this, we exploit differences in the timing of marijuana laws among states and find that they are substitutes. We show that unlike traditional national-level analysis, focusing on contiguous-border county pairs provides unbiased estimates of the effect of MMLs on alcohol sales. Specifically, alcohol sales in counties located in MML states decreased by 12.4%. Results are robust to including placebo effective dates for MMLs in treated states. Resume Marijuana et alcool: analyse transfrontaliere et donnees relatives a la vente au detail. Afin d'etudier la correlation entre les lois sur la marijuana medicale (LMM) et la consommation d'alcool, nous nous sommes appuyes sur les donnees de vente au detail de boissons alcoolisees dans differents comtes des etats-Unis entre 2005 et 2016. A cette fin, nous avons d'abord exploite le decalage dans le temps des mises en oe uvre des LMM dans les etats concernes, et avons decouvert qu'alcool et marijuana se substituaient l'un a l'autre. Nous montrons egalement qu'une analyse realisee sur des paires de comtes transfrontaliers, contrairement a une etude traditionnelle realisee a l'echelle nationale, permettait de fournir des evaluations fiables relativement a l'incidence des LMM sur les ventes d'alcool. Plus precisement, le volume mensuel des ventes d'alcool dans les comtes situes dans des etats ayant passe des lois sur la marijuana medicale a diminue de 12, 4 %. Les resultats restent robustes meme en integrant de fausses dates de mise en oe uvre des LLM dans les etats etudies.
