Fairbanks School of Public Health, Indianapolis, IN.https://hdl.handle.net/1805/22243Most peoples’ first exposure to alcohol, tobacco, and other drugs typically occurs during adolescence, a time when the brain changes rather dramatically. The maturation process of the adolescent brain is reflected in a greater propensity to take part in risky activities such as unprotected sex, reckless driving, and substance use. Alcohol, nicotine, and marijuana, the most commonly used substances by teens, have all been tied to disruptions in normal brain development. These structural changes are associated with higher rates of cognitive impairments and academic difficulties, higher rates of future substance use and substance use disorders, and higher rates of mood and psychotic disorders.en-USSubstance UseBrainAdolescenceAddictionTreatmentOther
