A survey of drug use on campus 11.19.08
35 percent of the 300 students surveyed said they have used drugs while at Yale. That puts the Yale student body’s drug use almost exactly on par with the average at other schools: 36.6 percent of undergraduates nationwide said in 2005 that they had used an illicit drug at least once in the previous year, according to a study by the National Center on Addiction and Substance Abuse at Columbia University.
