I can't believe anyone can be stupid enough to think cannabis is dangerous enough to merit criminalization.
What you can or cannot believe isn't important, the truth is that cannabis can have a devastating effect on the developing teenage mind. Even if you don't consider that enough to warrant criminalization, that does not justify insulting those of us who do.
By that measure, so is alcohol, or any number of other drugs that are sold over the counter. Yes it should be age restricted, but the point is that it is not any more dangerous than plenty of other substances that are legal. It's certainly less dangerous than cigarettes.
