Drug use by adolescents can have immediate as well as long-term health and social consequences. Cocaine use is linked with health problems that range from eating disorders to disability to death from heart attacks and strokes.96 Marijuana use poses both cognitive and health risks, particularly damage to pulmonary functions as a result of chronic use.97, 98 Hallucinogens can affect brain chemistry and result in problems with memory and learning new information.99 As is the case with alcohol use and smoking, illicit drug use is a risk-taking behavior that has potentially serious negative consequences.
NOTE: Use of "any illicit drug" includes any use of marijuana, LSD, other hallucinogens, crack, other cocaine, or heroin, or any use of other narcotics, amphetamines, barbiturates, or tranquilizers not under a doctor's orders. For 8th- and 10th-graders, the use of other narcotics and barbiturates has been excluded because these younger respondents appear to overreport use (perhaps because they include the use of nonprescription drugs in their responses). Data for 10th-graders for 2008 are not included because estimates are considered to be unreliable due to sampling error. See http://www.monitoringthefuture.org/data/09data.html#2009data-drugs.
