The author of "Marijuana Policy in Colorado" is Jeffrey Miron, the Cato Institute's director of economic studies. The document is classified as a working paper, meaning that it's in-process research being circulated to spark comment and debate.
Prior to legalization taking effect on January 1 of this year, Miron was among those who thought the move could have numerous positive economic effects. As seen in an April 2013 video shared by Cato and on view below, he mentions among several examples the possibility of law enforcement resources previously used for marijuana interdiction being freed up for other purposes.In the paper, however, Miron stops well short of boosterism. Here's an excerpt from the piece's summary section:
Supporters and opponents of such initiatives make numerous claims about state-level marijuana legalization. Advocates believe legalization reduces crime, raises revenue, lowers criminal justice expenditure, improves public health, improves traffic safety, and stimulates the economy. Critics believe legalization spurs marijuana use, increases crime, diminishes traffic safety, harms public health, and lowers teen educational achievement. Systematic evaluation of these claims, however, has been absent....The paper includes numerous graphics illustrating Miron's points. Here's a look at data concerning marijuana use by high schoolers: Miron's analysis: "The trend exhibits mild but temporary upward bumps in the years when medical marijuana is introduced and expanded, but the overall trend is downward and not materially affected by the changes in marijuana policy."The conclusion from this initial evaluation is that changes in Colorado's marijuana policy have had minimal impact on marijuana use and the outcomes sometimes associated with use. Colorado has collected non-trivial tax revenue from legal marijuana, but so far less than anticipated by legalization advocates.

"No measure indicates a significant change in crime after medical marijuana commercialization, legalization adoption or full legalization implementation," Miron writes.He sees a similar trend, or lack thereof, when it comes to fatal car crashes:
In his words, "No measure exhibits a substantial change at the time of marijuana policy changes."Such conclusions will undoubtedly cheer those in favor of legalization. But Miron offers less upbeat news in regard to "reduced expenditure on criminal justice activities. Here are two graphics....
...that Miron analyzes like so:Figure 14 shows state expenditure for police protection and incarceration. Police protection grows over time but shows no variation around the dates of marijuana policy changes. Incarceration also grows, but if anything more slowly after adoption and expansion of medical marijuana. Figure 15 shows employment in the three main components of criminal justice activity; police employment increases substantially between 2009 and 2010, but returns to trend within two years. Neither judicial and legal employment nor corrections employment shows any meaningful change after a marijuana policy change.Of course, marijuana advocates might argue that such changes for the good aren't happening because of entrenched behaviors and a refusal by many politicians and officials to accept a new reality. And fortunately, such discussions are precisely what the working paper is attempting to spur.
