Drug addiction is a preventable disease. Research has shown that prevention programs that involve the family, schools, communities, and the media are effective in reducing drug abuse. Although many events and cultural factors affect drug abuse trends, when youths perceive drug abuse as harmful, they reduce their drug taking. It is necessary, therefore, to help youth and the general public to understand the risks of drug abuse and for teachers, parents, and health care professionals to keep sending the message that drug addiction can be prevented if a person never abuses drugs.
