Is this really glamour? How is it helping, exactly? I don't see any purpose to unrestricted access to these substances, unless your goal is to shatter and/or destroy the lives of 20,000,000 Americans.
I'll add that I think people should have a choice, but rights cease being rights when they impose on the rights of others. Weed, tobacco, and alcohol are legal, but that doesn't mean there is no cost to society. People do stupid shit after smoking. Tobacco has health care implications. Alcohol destroys families. Free access to fent, heroin, crack, cocaine, lsd, meth, and even mdma is going to incur a very big cost. Those are non-starters. And while I think mdma can be used under medical care, abuse of that specific drug incurs a debt.
