What You Must Know About The Poisons in Your Medicine Chest. If you knew what we know about the most popular prescription and over-the-counter drugs, you'd be sick. That's why Dr. Douglass wrote Dangerous (Legal) Drugs. He gives you the low-down on 15 different categories of drugs: everything from painkillers and cold remedies to tranquilizers and powerful cancer drugs. Organized medicine should stop worrying about competition from alternative health practitioners, such as chiropractors and homeopaths, and clean up its own act. How can doctors expect their patients to have any confidence in their prescriptions or their advice on such life and death matters as cancer therapy, if patients are wondering how much money doctors are making because they are suggesting one particular line of therapy as opposed to another? Americans, barraged with warnings about the dangers of crack and other street drugs, have more to fear from the medicine they get from their doctor. Most Americans will not come into contact with crack, but they can get exposed to some lethal stuff, and be completely unaware of it, from their family doctor.
