| —Not available. † Not applicable. 1 Survey question changed in 1993; later data are not comparable to figures for earlier years. 2 Other illicit drugs include any use of LSD or other hallucinogens, crack or other cocaine, or heroin, or any use of other narcotics, amphetamines, barbiturates, or tranquilizers not under a doctor's orders. NOTE: Standard errors appear in parentheses. Standard errors were calculated from formulas to perform trend analysis over an interval greater than 1 year (for example, a comparison between 1975 and 1990). A revised questionnaire was used in 1982 and later years to reduce the inappropriate reporting of nonprescription stimulants. This slightly reduced the positive responses for some types of drug abuse. SOURCE: University of Michigan, Institute for Social Research, Monitoring the Future, selected years, 1975 through 2005.
