Well, I disagree. There is casual use of Meth. I casually partied in my first years here in the States. Three times. I never felt the need to become an habitual user. The last time I did not even realized I was high until I stopped fucking and noticed my knees were bleeding (after hours of doggy fucking a guy on a rough carpet). Shitty. It is just a stupid drug. And lethal if you get addicted.
