My friends doing good actually Camarel. One of the few who's found a life after doing that shit. He was at a party and someone just thrust a needle in his arm and that's all it took. He still smokes joints every now and then but other than that he's straight as an arrow.
Personally I think meth is worse than heroin. From the photos I've seen it's enough to make you depressed for a few days. But you wanna talk about withering away look up Layne Staley from Alice in Chains. Amazing voice, hell of a singer and musician, he couldn't get off heroin. When they found his body he had already been dead two weeks and he was listed as six one 86 pounds.
