Voters in Colorado and Washington on Tuesday approved measures allowing adults to use marijuana for any purpose, NBC News projected, marking an historic turning point in the slow-growing acceptance of marijuana usage.
In Massachusetts, voters also approved an initiative allowing people to use marijuana for medicinal purposes, NBC News projected. In Arkansas, a similar initiative failed, according to NBC News projections.
In all, voters in six states were being asked to decide on a wide array of laws around legalizing marijuana for medicinal or recreational purposes.
Colorado's Proposition 64 to the state's constitution makes it legal for anyone over the age of 21 to possess marijuana and for businesses to sell it.
"The voters have spoken and we have to respect their will," Colorado Gov. John Hickenlooper said in a statement. "This will be a complicated process, but we intend to follow through. That said, federal law still says marijuana is an illegal drug so don't break out the Cheetos or gold fish too quickly."
