Marijuana Arrests in Colorado After the Passage of Amendment 64
This report provides comprehensive data on marijuana charges and arrests in Colorado before and after the passage of Amendment 64 in 2012. The report compiles and analyzes data from the county judicial districts, as well as various law enforcement agencies via the National Incident Based Reporting System (NIBRS). The report finds that marijuana arrests have drastically plummeted in Colorado following the passage of Amendment 64.
(Updated 4/24/15) Following the publication of this report last month, the Drug Policy Alliance (DPA) was contacted by the Colorado Judicial Branch (CJB). The CJB notified DPA that the data CJB provided to DPA was incorrect. According to CJB’s Court Programs Analyst, the query used by CJB to compile the data “duplicated and in some cases quadrupled charge counts” for the years 2010 and 2011.
While it’s unfortunate that we were provided incorrect data by the Colorado Judicial Branch, the report’s good news remains the same: Across all categories, marijuana arrests have drastically plummeted in Colorado following the passage of Amendment 64.
