Why are so many dangerous psychotropic drugs being allowed on the market?

One reason may be the revolving door between government, academia and the drug industry, where panels recommending psychotropic drug approval have long been filled with psychiatrists with financial ties to drug companies.

Knowing nothing about the mind, the brain, or about the underlying causes of mental disturbance, psychiatry still sears the brain with electroshock, tears it with psychosurgery and deadens it with dangerous drugs.

CCHR created the psychiatric drug side effects search engine to provide the public with easily understandable information on the documented risks of psychiatric drugs.
It is provided as a free public service by CCHR International: https://www.cchrint.org/psychdrugdangers/
Your search will yield a summary of the following three different sources of data on documented psychiatric drug risks:

1. International drug regulatory warnings.
2. Studies published in worldwide medical journals.
3. Adverse reaction reports filed with the U.S. Food and Drug Administration between 2004-2012, by doctors, pharmacists, health care providers, attorneys and consumers.
Only by providing all the facts about the risks of psychiatric treatment can we possibly reduce the number of victims who unfortunately learn this truth through personal tragedy.
CCHR provides information that psychiatrists and pharmaceutical companies do not want you to know.
By educating yourself with the facts about psychiatry, you will have the information you need to never become a victim of this vicious pseudo-science.
