To say that it's about time is an understatement in the extreme. For half a century, the war on drugs has been almost a complete failure. I say "almost" because its real purpose was to help elect politicians, and that it did handily. As for the rest, no sane person ever believed that you could actually prevent the sale and use of drugs. It was always a fantasy.
How ironic, though, that when marijuana finally becomes legal it will not be due to common sense or good governing but to financial desperation. But I suppose one shouldn't look a gift horse in the mouth.
