I would definitely prefer not to have chemical compounds that haven't been demonstrated effective marketed as consumer medical products. I'm not sure how that connects to the thread, though.
While there are some drugs that are clearly effective, there are big problems in Big Pharma's approach to clinical trials, including burying half the trials' results and poor experiment design. And once a drug makes it to market, expanding that market without testing becomes a priority. Do you think Risperdal was a one-off, or is it a representative case study of how drugs are marketed by at least a major part of Big Pharma?
