Is it impurities in meth that give you psychosis? I was of the impression that often it was due to sleep deprivation due to being on meth and not sleeping for days.
All forms of meth give you psychosis, slowly, with continued use. The sleep deprivation adds to that. Meth created via the P2P method is apparently considerably worse for you, and leads to psychosis at a much higher rate than ephedrine methods: https://www.theatlantic.com/magazine/archive/2021/11/the-new...
