Mason Tvert (L) and Brian Vicente pose in their offices in Denver, Colorado, May 25, 2012. The two are the leaders of a campaign calling for the legalization of an ounce of marijuana, and creating a legal framework so the drug's sale could be regulated and taxed by the state as alcohol is today. The Rocky Mountain State already allows the use of marijuana for medical purposes such as severe pain relief, and some communities have embraced it enthusiastically. The prevalence of medical marijuana dispensaries in Denver has moved pot into the mainstream in Colorado's capital city, advocates and political leaders say. In Denver County, home to about 600,000 people, one in every 41 residents is a registered medical marijuana patient, leading to chuckles about the "Mile High City." Picture taken May 25, 2012.
