Using Controlled Substances

Controlled substances are those which may lead to tolerance, withdrawal, abuse, dependence and addiction. Controlled substances are more tightly regulated and controlled by the FDA so as to prevent excessive misuse and abuse.

Most controlled substances are capable of producing dependence, either physical or psychological. Physical dependence refers to the changes that have occurred in the body after contined use of a drug that requires the continued administration of the drug to prevent a withdrawal episode. Psychological dependence refers to the perceived "need" or "craving" for a drug. Those who are psychologically dependent on a particular substance often feel that they cannot function without use of that substance. While physical dependence disappears within days or weeks after drug use stops, psychological dependence can last much longer.

Today, the majority of young people have used an controlled substance by the time they leave high school and about 25 percent of all seniors are current users. The actions associated with teen drug use often result in tragic consequences and likely harm to others, themselves, and their families.
