if you're constantly high, maybe not. but smoking on your down time, I don't see why it's that bad. there are far worse things to be doing, and if you can be cautious and responsible, I don't see the trouble. all of us can control how cautious and responsible we are with drugs. there is such a thing as quitting. just because someone does it a lot doesn't mean they always will. you have to choose drugs before they can choose you, and sticking with marijuana and using caution makes it far easier to make it your own choice.
