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.
