A book I recommended elsewhere in this thread, http://www.amazon.com/Anatomy-Epidemic-Bullets-Psychiatric-A..., does an admirable job of researching the history and results (medical, scholarly, social and financial) of psychological drugs in the US.
About how there has been an enormous rise in the rates of mental illness over the last 50 years. And despite the fact that the APA says it's because we've gotten better at diagnosing mental illness, the bulk of the evidence points to the fact that psychiatric drugs are causing diseases that used to mostly get better with time to become both more severe and long lasting.
Or you read? If SSRIs are so helpful, then why does the majority of the research suggest that this isn't the case?[1] If you think they are helpful, then the burden of proof is on you to show that the science is incorrect.
