College and university students drink more alcohol than their nonstudent peers and exhibit 2.5 times the general population’s rate of substance abuse.

Fraternity and sorority members report nearly twice the binge-drinking rate of nonmembers.

Since 1993, campus smoking rates have declined, alcohol use has been steady, and abuse of prescription opioids, stimulants, tranquilizers, and sedatives has increased, as has marijuana use.
