I have many friends, or ex-friends I should say, in that area that have fallen to this drug recently. The guys have a little bit more time than the girls it appears. Not that it makes any difference but the girls are toast after the first time. The guys seem to think they can keep it together for a while and then BAM!
Full disclosure: I am a former rock musician and I have had vast experience in these matters. People can say what they want about drugs I don't care, I have seen this stuff do people in that were recreational drug users for years.
You're right.... Meth is not merely a recreational drug and I've seen the same thing.
