Basically they say smoke is deadly, causes cancer, makes you smell, etc.
Haha, unrelated, but I know this guy who went to Amsterdam for New Year's. He's a waiter, 20-odd, and likes to party. So.. imagine what he did. We met up with him yesterday, and there was a leaf on one of his lamps. I started giggling, and my dad was like "It's a maple leaf." Which, pssh, it was totally an Amsterdam leaf. So.. He kept trying to convince me that it was maple, and then oak, and then palm. And then we left. And, so not knowing what a pot-leaf actually looks like, I asked Betty and she was like, "Yeah, it's cannabis. But it's perfectly legal to have it, just not buy it." Guess you gotta steal your pot kids. 'Cos.. two wrongs make a right or something?
On a serious note, don't do drugs.
