It is controversial, but in the real world it's gaining an incredible amount of traction. One only needs to look at Washington and Colorado for examples, with many other states OKing medical marijuana. Honestly, I find that to be okay. Look at the stigma attached to it...it's all but completely incorrect. Even the Fed has labeled it something it isn't - a narcotic. Posts like that should be okay, even though many people have an aversion to it for one reason or another. Frankly, I can't wait for people to have that aversion to tobacco and alcohol, completely flipping the current story.
But, just as with anything, transitions are hard.
