“Teenage drinking has been declining since 1999, but students vastly overestimate their classmates’ use of alcohol, drugs, and cigarettes. For example, a study conducted at a Midwestern high school when teenage alcohol use was peaking found that students believed that 92% of their peers Frank alcohol and 85% smoked cigarettes. When researchers surveyed the school to unearth the actual statistics, they learned that 47% of students had consumed alcohol and 17% smoked.”
