the Departments of Defense and Veterans Affairs combined have spent over $4.5 billion on antidepressants, antipsychotics, and antianxiety drugs. A June 2010 internal report from the Defense Department’s Pharmacoeconomic Center at Fort Sam Houston in San Antonio showed that 213,972, or 20 percent of the 1.1 million active-duty troops surveyed, were taking some form of psychotropic drug: antidepressants, antipsychotics, sedative hypnotics, or other controlled substances.
