Not just for medicinal purposes, but for recreational purposes, too.

At Rolling Stone, a smart blog post by Julian Brookes on what happens when the first state says "yes" to weed.

When that happens, expect one of two things – either: the federal government, in deference to democratic principles, will decline to enforce its ban on marijuana, creating space for the state to be a "laboratory of democracy," working out its new policy by trial and error, learning as it goes, creating a trove of hard-earned lessons to guide the states that (inevitably) will follow; or: the federal government will bide its time and then come down hard, busting growers and retailers, seizing land and property (or, just as effective, threatening to), going after banks that serve pot business, and doing whatever else it takes to shut down the state's legalization push.
