Smoking, Drinking, and Drug Use in Young Adulthood

Why do some young adults substantially change their patterns of smoking, drinking, or illicit drug use after graduating from high school? In this book, the authors show that leaving high school and leaving home create new freedoms that are linked to increases in the use of cigarettes, alcohol, marijuana, and cocaine. They also show that marriage, pregnancy, and parenthood create new responsibilities that are linked to decreases in drug use.
