No, Sergemak, it couldn't be meth. You have to use it for months to have physical effects of withdrawal. And it's too strong to don't notice its effects. (Btw, one of well known side effects is crazy boost of sexual desire, there's even stories about how heterosexuals may have gay sex if they can't find opposite sex partner.)

If people were diagnosed as drug addicts, they were told what drug it was, there would be official evidences, analyses, medical conclusions. But all we have is just some doubtful stories.
