"The Cross-Border Spillover Effects of Recreational Marijuana Legalization"

The title of this post is the title of this notable new research by Zhuang Hao and Benjamin Cowan published by the National Bureau of Economic Research.  Here is the abstract:

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.  We do not find evidence that marijuana sale/manufacture arrests, DUI arrests, or opium/cocaine possession arrests in border counties are affected by RML.
