Plus it's devastating physically. The welts, scratching, paranoia, food avoidance, tooth eating qualities, etc, are pretty unique. It wrecks your body pretty fast. Serious meth addicts seem to age at a 10x+ factor compared to other addicts. Twentyish old people look 40+ after just a year or so after getting hooked.
I'm pretty liberal, but I would fight against legalization of meth. It's really terrible. Meet a girl in her 20's that's been on it a year or two and you might see the issue. Not yet 30, but no teeth left, massive skin issues on their face/arms/upper torso from the welts/scratching, emaciated, and infertile. Also often HIV and/or Hep-C from trading sex for drugs. That shit is pure poison.
