The Department of Justice paid for a new study on the impact of marijuana legalization that ended up showing cannabis programs do not seem to negatively affect neighboring, non-legal states.
The paper’s authors said they sought to answer three questions in these analyses of state-level data:
1) How does legalization impact law enforcement resources in legal states?
2) How does it impact those resources in bordering, non-legal states? and 3) What does legalizing cannabis mean for drug trafficking?
To assess the impact, the researchers looked at statistics on drug possession and distribution arrests in a mix of legalized states and nearby ones that maintained prohibition. According to that data, legalization didn’t cause the sky to fall.
“Legalizing marijuana did not have a noticeable impact on indicators in states that bordered those that legalized,” the study concluded, adding that “there were no noticeable indications of an increase in arrests related to transportation or trafficking offenses in states along the northern or southern borders.”
That is evidently a finding that the Justice Department does not want the public to think it endorses. At the beginning of the report—and on every other page—there’s a disclaimer stressing that while federal funds were used to support the research, “[o]pinions or points of view expressed are those of the author(s) and do not necessarily reflect the official position or policies of the U.S. Department of Justice.”
Here’s what the study authors, who are affiliated with the Justice Research and Statistics Association, found:
Not surprisingly, arrests for marijuana possession dropped significantly in Washington after the state legalized cannabis in 2012. Those arrests continued to drop after retails sales became available. Distribution arrests followed a similar trend.
