Teen Drug Abuse: Symptoms & Signs

Teen drug abuse is the abuse or misuse of drugs of any type by teenagers. Teen drug abuse can involve legal or illegal drugs, including prescription or over-the-counter medications.

Symptoms and signs of teen drug abuse are extremely varied and depend to a certain extent on the substance being abused. Symptoms and signs can include depression, bad grades, poor hygiene, avoiding eye contact, food cravings (munchies), a smoky smell on breath or clothing, tiredness, and missing curfew. Other signs and symptoms can include secretive behavior, loss of interest in once-pleasurable activities, laughing for no reason, or bloodshot eyes.
