How psychopharmacology has usurped the role of psychotherapy in our society, to the great detriment of the patients involved. William Glasser describes in Warning: Psychiatry Can Be Hazardous to Your Mental Health the sea change that has taken place in the treatment of mental health in the last few years. Millions of patients are now routinely being given prescriptions for a wide range of drugs including Ritalin, Prosac, Zoloft and related drugs which can be harmful to the brain. A previous generation of patients would have had a course of psychotherapy without brain–damaging chemicals. Glasser explains the wide implications of this radical change in treatment and what can be done to counter it.
