DENVER (AP) — Four more states legalized marijuana for all adults last year, and more than half the states now allow pot use by people with a long list of ailments. But don't break out the Goldfish and Cheetos just yet.
That's what the Colorado governor famously said after his state and Washington became the first to legalize recreational pot in 2012.
The joke belies an important truth about the nation's evolving marijuana experiment: It's too soon to say how these experiments will turn out. States wading into legal weed are in direct defiance of federal drug law, so they're on their own when it comes to regulating a drug that had been illegal for almost a century.
