Effect Of Medical Marijuana Legalization On Crime Rates And Limitations Of Data: "Given that the current results failed to uncover a crime exacerbating effect attributable to MML, it is important to examine the findings with a critical eye. While we report no positive association between MML and any crime type, this does not prove MML has no effect on crime (or even that it reduces crime). It may be the case that an omitted variable, or set of variables, has confounded the associations and masked the true positive effect of MML on crime.
Average Police Time Taken Per Marijuana Arrest: "In those eleven years the NYPD made a total of 439,056 possession-only arrests.

That is the equivalent of having 31 police officers working eight hours a day, 365 days a year, for 11 years, making only marijuana possession arrests."
