Do you want someone coming up to you, please don't smoke weed? Cmon, i'm not denying any damage meth would cause to one in the long term, but in the short-term it's ridiculous, other than loss sleep, and anxiety. Your mere opinion on you shouldn't try meth it's bad, is no different than some idiot coming up to you and saying "don't smoke weed, because it gets you stoned, and it's a waste of money." Personally I tried meth a couple of times, and I didn't enjoy it either time.

I'm sure you'll be speaking to a choir in the lounge.
