Pot in Colorado could be confined to state residents

DENVER -- Colorado may consider allowing only state residents to use marijuana recreationally after voters approved a measure to legalize use of the drug for non-medical purposes. A marijuana regulatory group appointed by Gov. John Hickenlooper started work Thursday penciling the nitty-gritty details of pot regulation. The group members won't make rules, but they'll recommend to the governor and the Legislature how Colorado should become the nation's first to regulate marijuana like alcohol.
