註釋We examine the spillover effects of recreational marijuana legalization (RML) in Colorado and Washington on neighboring states. We find that RML causes a sharp increase in marijuana possession arrests in border counties of neighboring states relative to non-border counties in these states. RML has no impact on juvenile marijuana possession arrests but is rather fully concentrated among adults. Using separate data on self-reported marijuana use, we show this is accompanied by an increase in use in neighboring states relative to non-neighboring states. We do not find conclusive evidence that marijuana sale/manufacture arrests, DUI arrests, or opium/cocaine possession arrests in border states are affected by RML.
