Marijuana saleswoman Marissa Dodd (center) talks to a customer about different varieties of marijuana available at the Dr. Reefer marijuana dispensary April 20, 2010 at the University of Colorado in Boulder, Colorado. Dr. Reefer is one of several legal marijuana dispensaries in Boulder, and sell their different varieties of marijuana to anyone possessing a medical marijuana card issued by the state. Colorado, one of 14 states to allow use of medical marijuana, has experienced an explosion in marijuana dispensaries, trade shows and related businesses in the last year as marijuana use becomes more mainstream here.
Two Western states, Colorado and Washington, have become the first states to legalize recreational marijuana.
Voters there approved ballot measures that remove criminal and civil penalties for the adult possession of cannabis, but it's likely the measures will result in a confrontation between these states and the federal government, which prohibits use of the drug.
To discuss the future of these measures, we have with us Beau Kilmer, Co-Director of the RAND Drug Policy Research Center.
