I am the parent of a teenage son who has been given a lot of psychoactive medication by well- meaning doctors during his short life. I have watched him get sicker and sicker. Every week I pick up the paper and read that the pharmaceutical industry is more concerned with making profits than with making sure their medications are efficacious, and are designed to treat the right subset of people. My son has been on dozens of different medications, and is typically on 4 or 5 at once. I am powerless to stop this while he is under 21, since my wife has agreed to his being medicated to this extent.
