There isn't much attention paid to prescription drug abuse, except perhaps when a Hollywood star dies from an overdose. However, it is estimated that nearly one in five Americans has used prescription drugs for nonmedicinal reasons, and 15 percent may be abusing prescription drugs. This silent epidemic has become the leading cause of addiction. The dangers of prescription drug abuse are growing at an exponential rate. Between 1992 and 2002, the number of prescriptions written increased by 61 percent, but the number of prescriptions written for opiates increased by almost 400 percent. Opiates reflect three-quarters of all prescription drugs abused. According to a report this month by the Centers for Disease Control and Prevention, hospitalizations for poisoning by prescription opioids, sedatives and tranquilizers jumped 65 percent from 1999 to 2006. One-third of new addicts report that their first drug experience was with prescription drugs. More and more teenagers are turning away from street drugs and using prescription drugs to get high.
