"Since DSHEA became law, substances as varied as paint stripper, bat shit, toad venom, and lamb placenta have all been imported from overseas, bottled up---often by people with no scientific or health backgrounds---and marketed as dietary supplements to unsuspecting American consumers. Many supplements have been tainted with salmonella, arsenic, lead, pesticides, unapproved foreign prescription drugs, as well as garden-variety carcinogens. And despite their New-Age health aura, a significant portion of these "natural supplements" are stimulants, depressants, and other mood-enhancers that some medical experts believe would be classified as drugs if they were synthetic. A surprising number of these products are addictive."

If I read this correctly, I could sell rat poison labeled "Super-Happy Energy Powder" and get away with it for a year or two.

Yeah, its pretty funny. From what I understand, a lot of these supplement companies are HQ'd in Utah. Do you know who spearheaded the deregulation of the supplement industry? That's right, your friendly Utah senior senator, Orin Hatch.
