4:58PM EST December 10. 2012 - FORT COLLINS, Colo. -- Colorado Gov. John Hickenlooper on Monday signed a declaration formalizing the voter-approved amendment that makes it legal for those 21 and older to use marijuana.
On Election Day, voters approved Amendment 64 which called on the state to regulate marijuana like alcohol. The amendment allows for limited use, possession and cultivation of marijuana.
"This is a truly historic day," said Mason Tvert, co-director of the campaign to pass the measure. "From this day forward, adults in Colorado will no longer be punished for the simple use and possession of marijuana."
