On its own, no. Like I said above, those already experiencing psychological issues, which I don't believe AD/HD is. I'm talking borderline personality disorders, schizophrenia, bi-polar disorder. Since before I started working with the SMI community back in '91 or '92, the "expert" researchers have been arguing over what used to be called "dual diagnosis" (it is something else now), that being were people mentally ill and attracted to drug use as self-medication or were they already in a fragile mental state, which snapped after using street drugs. Only one study I've seen mentioned attempted to correlate prescription drugs in youth to researching this theory. As with most anything that attempts to show a connection between Big Pharma and health issues, it was the only time I'd seen a mention of it. And even if Ritalin, Zoloft, Prozac, Paxil, Celexa, ARE used by millions upon millions of people safely every single day (and they are), that doesn't mean that they aren't a contributing factor in a chain of events. It is societal hypocrisy to say it isn't prescription drugs that are used by millions of people when just a few do bad things, yet we are willing to blame the illegal drug when a few of the millions of meth heads are the bad apples. But studies have been done with severly mentally ill that have been on street drugs...because that IS ok to study. I've seen hyperactive kids settle down when given a good dose of caffiene. Why aren't they prescribing espresso? follow the money Jon
