I've had few friends who tried methamphetamine. Two of them were completely turned off by it but one got addicted and very quickly disappeared (we still wonder what happened to him). They were all just hardcore dudes from bad homes hanging out with other hardcore dudes from bad homes. It seems like the young folks who try meth do it because they know someone attractive or otherwise fun to be around who is doing it. It is my completely uneducated guess that the first person to get addicted to meth, had it perscribed by a medical doctor.
