†Not applicable.
\1\Survey question changed in 1993; 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, 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 one 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.
