"[...]he tried to put the dangers of methamphetamine in perspective, noting that the drug is a government-approved treatment for narcolepsy and attention deficit hyperactivity disorder (ADHD). He cited his own research finding that methamphetamine has “the same effects” as a more familiar ADHD drug, Adderall, which has a “nearly identical” chemical structure." The aesthetic appearance of chemical structure has absolutely nothing to do with the effect of a drug. I seriously question this guy's motives. I would recommend that no one ever try meth. Just like I would recommend no one try heroin. I think meth and heroin are much closer together on their addictive potential than crack, so I don't understand why he would lump crack together with meth, and leave out heroin. Something's fishy about this article.
