• The only way legalizing marijuana in California would significantly influence DTO revenues and the related violence is if California-produced marijuana is smuggled to other states at prices that outcompete current Mexican supplies. The extent of such smuggling will depend on a number of factors, including the response of the U.S. federal government.

• If marijuana is smuggled from California to other states, it could undercut sales of Mexican marijuana in much of the U.S., cutting DTOs' marijuana export revenues by more than 65 percent and probably by 85 percent or more. In this scenario, the DTOs would lose approximately 20% of their total drug export revenues.

The report also finds the Government's figures of cartel involvement in marijuana in the U.S. greatly exaggerated:

The RAND study also finds that the often-cited claim that marijuana accounts for 60 percent of gross drug export revenues of Mexican drug trafficking organizations is not credible. RAND's exploratory analysis on this point suggests that 15 percent to 26 percent is a more credible range.

...."No publicly available source verifies or explains the mythical 60 percent figure and subsequent government analyses revealed great uncertainty about the estimate," said study co-author Jonathan P. Caulkins, the H. Guyford Stever Professor of Operations Research at Carnegie Mellon University's Heinz College and Qatar campus. "Our analyses suggest that smuggling marijuana across the Southwest border accounts for 15 to 26 percent of the export revenues generated by Mexican drug trafficking organizations."

Under Prop 19, people over the age of 21 awill be allowed to cultivate marijuana on a 5-foot-by-5-foot plot and possess, process, share or transport up to one ounce of marijuana.

In July, 2010, Rand issued a report called Altered States, that found legalization in California could drop marijuana prices to $38.00 an ounce.

The RAND Drug Policy Research Center is a joint project of RAND Health and the RAND Safety and Justice program within RAND Infrastructure, Safety, and Environment.

The goal of the RAND Drug Policy Research Center is to provide a firm, empirical foundation upon which sound drug policies can be built.

A lot of law professors support Prop 19. For more on why legalization is the way to go, see Yes on 19, Drug Policy Alliance, NORML , Just Say Nowand Marijuana Policy Project, to name a few.

The war on drugs has failed. It's time to go in a different direction. If you live in California, please help get out the vote. Turnout is key.
