Your other link was better (which isn't saying much). There are lawsuits out there for patients who had a stroke and were on Plavix. Which is ridiculous. There were patients who sued Merck after being on samples for a week. Ridiculous. Now, if there was a nationwide class action suit, you'd have something. Right now, the data's not there. And a "Health and Nutrition" advocate (read: anti-pharmaceutical) saying that drugs are bad is about as predictable as the sun rising in the east.
From your link: emergence of suicidal ideation or behavior has been observed with many antidepressant pharmacotherapies
Being observed in a clinical trial is interesting, but I would imagine that placebo also had some emergent suicidal ideation.
As afar as the pharmaceutical industry being some sort of unregulated Wild Wild West, it's simply not the case. The pharmaceutical industry is more frightened of a lawsuit than WWIII.
A good peer-reviewed study in a respectable journal would go quite a ways. I'm sure there's researchers working on it as we speak.
