Why do adolescents take drugs? Adolescents experiment with drugs or continue taking them for several reasons, including: To fit in: Many teens use drugs âbecause others are doing itââor they think others are doing itâand they fear not being accepted in a social circle that includes drug-using peers. To feel good: Abused drugs interact with the neurochemistry of the brain to produce feelings of pleasure. The intensity of this euphoria differs by the type of drug and how it is used. To feel better: Some adolescents suffer from depression, social anxiety, stress-related disorders, and physical pain.
PRESCRIPTION DRUG ABUSE: A SERIOUS PROBLEM. Recreational use of prescription drugs is a serious problem with teens and young adults. National studies show that a teen is more likely to have abused a prescription drug than an illegal street drug. Many teens think prescription drugs are safe because they were prescribed by a doctor. But taking them for nonmedical use to get high or âself-medicateâ can be just as dangerous and addictive as taking illegal street drugs. There are very serious health risks in taking prescription drugs. This is why they are taken only under the care of a doctor. And even then, they have to be closely monitored to avoid addiction or other problems.
