Colorado Gov. John Hickenlooper (D) officially signed the state's proclamation legalizing marijuana on Monday, the Denver Post reports:

Hickenlooper, a Democrat, signed the proclamation that officially places Amendment 64 into the constitution. And he announced the creation of a task force to attempt to work out the many legal and logistical details that must accompany the amendment, which makes the use, possession and limited home-growing of marijuana legal for anyone 21 and older.
