"The similarities between street drug abuse and psychotropic prescription drug use are disturbing. Both types are toxic. Both can cause psychosis, damage the brain and other organs, and even cause death. And neither type of mind-altering drugs, legal or illegal, treats disease. It's important to recognize that the only significant difference between many prescription psychotropic drugs and street drugs such as "speed" and "downers" is that prescription drugs are legal."
