I'm against drunk driving, yes. I'm also against pilots flying without any sleep. But I would disagree with the assertion that anyone who stays up late belongs in prison.
Sometimes the "cure" (in this case, prison time) is worse than the "disease" (marijuana use).
I've been pretty happy about cigarettes getting gradually outlawed, now I'm supposed to be cheering the rise of marijuana? As if we don't have enough junkies already.
