Today, I think that marijuana use should be safe, legal...and yet probably more rare than it is now. For one thing, marijuana use may be relatively safe..on your couch, but driving while stoned is highly dangerous, and I'm not sure if law enforcement is well positioned to prevent it. I also worry that -- at a time when American students are falling behind their peers in other industrialized nations -- too many kids will too easily get their hands on a drug that makes them even more stupid. The massive social problems that Americans face today -- like income inequality, or the new threats to voting rights -- won't be solved by the chronically buzzed. As Husker Du famously said, walking around with your head in the clouds, makes no sense at all.
