The other problem with it is that it kills motivation. But that doesn't necessarily mean it should be illegal. As long as someone is over age and they're not hurting anyone else, I kind of see marijuana the same as smoking cigarettes and drinking alcohol-if you're grown you're free to make bad choices as long as you don't hurt anyone else, but don't expect someone else to pay for your bad choices. If you're going to sit around and get high and can't support yourself, you're on your own. You are responsible for the consequences of your bad choices.
