Whoa there yourself! I thought I made it clear that the bit about criminalization was just a "bad joke" (my words). I was just pointing out that if we're going to talk about the dangers of cannabis, we should not be comparing the dangers of cannabis against the dangers of abstaining from cannabis, but we should be comparing those dangers against other risks which we consider completely acceptable, like World of Warcraft.
These threads can easily get out of hand when people think that other people are misinterpreting other people, a kind of chain of misinterpretation.
