NOTE: The population distributions for the 1993, 1994, and 1995 NHSDAs are post-stratified to population projections of totals based on the 1990 decennial census. The 1979 NHSDA used population projections based on the 1970 census; NHSDAs from 1982 through 1992 used projections based on the 1980 census. The change from one census base to another has little effect on estimated percentages reporting drug use, but may have significant effect on estimates of number of drug users in some subpopulation groups.
NOTE: Estimates for 1979 through 1993 may differ from estimates for these survey years that were published in other NHSDA reports. The estimates shown here for 1979 through 1993 have been adjusted to improve their
comparability with estimates based on the new version of the NHSDA instrument that was fielded in 1994 and subsequent NHSDAs. For 1979 and 1982, estimates are not shown (as indicated by --) where (a) the relevant
data were not collected, or (b) the data for those drugs were based on measures that differed appreciably from those used in the other survey years. Consequently, adjustments to the 1979 and 1982 data were made only for
those drugs whose measures were comparable to those in the other survey years. Because of the methodology used to adjust the 1979 through 1993 estimates, some logical inconsistency may exist between estimates for a
given drug within the same survey year. For example, some adjusted estimates of past year use may appear to be greater then adjusted lifetime estimates. These inconsistencies tend to be small, rare and not statistically
significant.

NOTE: The population distributions for the 1993, 1994, and 1995 NHSDAs are post-stratified to population projections of totals based on the 1990 decennial census. The 1979 NHSDA used population projections based on the 1970 census; NHSDAs from 1982 through 1992 used projections based on the 1980 census. The change from one census base to another has little effect on estimated percentages reporting drug use, but may have significant effect on estimates of number of drug users in some subpopulation groups.
NOTE: Estimates for 1979 through 1993 may differ from estimates for these survey years that were published in other NHSDA reports. The estimates shown here for 1979 through 1993 have been adjusted to improve their
comparability with estimates based on the new version of the NHSDA instrument that was fielded in 1994 and subsequent NHSDAs. For 1979 and 1982, estimates are not shown (as indicated by --) where (a) the relevant
data were not collected, or (b) the data for those drugs were based on measures that differed appreciably from those used in the other survey years. Consequently, adjustments to the 1979 and 1982 data were made only for
those drugs whose measures were comparable to those in the other survey years. Because of the methodology used to adjust the 1979 through 1993 estimates, some logical inconsistency may exist between estimates for a
given drug within the same survey year. For example, some adjusted estimates of past year use may appear to be greater then adjusted lifetime estimates. These inconsistencies tend to be small, rare and not statistically
significant.
1 Any Illicit Drug indicates use at least once of marijuana or hashish, cocaine (including crack), inhalants, hallucinogens (including PCP and LSD), heroin, or any prescription-type psychotherapeutic used nonmedically. Any Illicit Drug Other than Marijuana indicates use at least once of any of these listed drugs, regardless of marijuana use; marijuana users who also have used any of the other listed drugs are included.
2 Nonmedical use of any prescription-type stimulant, sedative, tranquilizer, or analgesic; does not include over-the-counter-drugs.
3 "Binge" Alcohol Use is defined as drinking five or more drinks on the same occasion on at least one day in the past 30 days. By "occasion" is meant at the same time or within a couple hours of each other. Heavy Alcohol Use is
defined as drinking five or more drinks on the same occasion on each of five or more days in the past 30 days; all Heavy Alcohol Users are also "Binge" Alcohol Users.

NOTE: The population distributions for the 1993, 1994, and 1995 NHSDAs are post-stratified to population projections of totals based on the 1990 decennial census. The 1979 NHSDA used population projections based on the 1970 census; NHSDAs from 1982 through 1992 used projections based on the 1980 census. The change from one census base to another has little effect on estimated percentages reporting drug use, but may have significant effect on estimates of number of drug users in some subpopulation groups.
NOTE: Estimates for 1979 through 1993 may differ from estimates for these survey years that were published in other NHSDA reports. The estimates shown here for 1979 through 1993 have been adjusted to improve their comparability with estimates based on the new version of the NHSDA instrument that was fielded in 1994 and subsequent NHSDAs. For 1979 and 1982, estimates are not shown (as indicated by --) where (a) the relevant data were not collected, or (b) the data for those drugs were based on measures that differed appreciably from those used in the other survey years. Consequently, adjustments to the 1979 and 1982 data were made only for those drugs whose measures were comparable to those in the other survey years. Because of the methodology used to adjust the 1979 through 1993 estimates, some logical inconsistency may exist between estimates for a given drug within the same survey year. For example, some adjusted estimates of past year use may appear to be greater then adjusted lifetime estimates. These inconsistencies tend to be small, rare and not statistically significant.
1 Any Illicit Drug indicates use at least once of marijuana or hashish, cocaine (including crack), inhalants, hallucinogens (including PCP and LSD), heroin, or any prescription-type psychotherapeutic used nonmedically. Any Illicit Drug Other than Marijuana indicates use at least once of any of these listed drugs, regardless of marijuana use; marijuana users who also have used any of the other listed drugs are included.
2 Nonmedical use of any prescription-type stimulant, sedative, tranquilizer, or analgesic; does not include over-the-counter-drugs.
3 "Binge" Alcohol Use is defined as drinking five or more drinks on the same occasion on at least one day in the past 30 days. By "occasion" is meant at the same time or within a couple hours of each other. Heavy Alcohol Use is defined as drinking five or more drinks on the same occasion on each of five or more days in the past 30 days; all Heavy Alcohol Users are also "Binge" Alcohol Users.

NOTE: The population distributions for the 1993, 1994, and 1995 NHSDAs are post-stratified to population projections of totals based on the 1990 decennial census. The 1979 NHSDA used population projections based on the 1970 census; NHSDAs from 1982 through 1992 used projections based on the 1980 census. The change from one census base to another has little effect on estimated percentages reporting drug use, but may have significant effect on estimates of number of drug users in some subpopulation groups.
NOTE: Estimates for 1979 through 1993 may differ from estimates for these survey years that were published in other NHSDA reports. The estimates shown here for 1979 through 1993 have been adjusted to improve their comparability with estimates based on the new version of the NHSDA instrument that was fielded in 1994 and subsequent NHSDAs. For 1979 and 1982, estimates are not shown (as indicated by --) where (a) the relevant data were not collected, or (b) the data for those drugs were based on measures that differed appreciably from those used in the other survey years. Consequently, adjustments to the 1979 and 1982 data were made only for those drugs whose measures were comparable to those in the other survey years.
Because of the methodology used to adjust the 1979 through 1993 estimates, some logical inconsistency may exist between estimates for a given drug within the same survey year. For example, some
adjusted estimates of past year use may appear to be greater then adjusted lifetime estimates. These inconsistencies tend to be small, rare and not statistically significant.

1 The numerator of each rate equals the number of persons who first used the drug in the year (times 1000). The denominator of each rate equals the number of persons who were exposed to risk of first use during the year, weighted by their estimated exposure time measured in years. For example, for the age group 12-17 in 1990, the denominator is the sum of three components:
(1) those persons 12-17 years old in 1990 who first used the drug in 1989 or earlier, times a weight of zero. The weight is zero since they had zero exposure to the risk of first use in 1990.
(2) those who first used the drug in 1990 times a weight of .5. The weight of .5 assumes that these people, on average, first used the drug at midyear and consequently have a half year of exposure (i.e. the first half of the year.)
(3) those who never used, or those who first used the drug in 1991 or later, times a weight of one. The weight of one assumes their exposure to the risk of first use during 1990 was for the whole year.
Each person is also weighted by his/her sample weight.

1 The numerator of each rate equals the number of persons who first used the drug in the year (times 1000). The denominator of each rate equals the number of persons who were exposed to risk of first use during the year, weighted by their estimated exposure time measured in years. For example, for the age group 12-17 in 1990, the denominator is the sum of three components:
(1) those persons 12-17 years old in 1990 who first used the drug in 1989 or earlier, times a weight of zero. The weight is zero since they had zero exposure to the risk of first use in 1990.
(2) those who first used the drug in 1990 times a weight of .5. The weight of .5 assumes that these people, on average, first used the drug at midyear and consequently have a half year of exposure (i.e. the first half of the year.)
(3) those who never used, or those who first used the drug in 1991 or later, times a weight of one. The weight of one assumes their exposure to the risk of first use during 1990 was for the whole year.
Each person is also weighted by his/her sample weight.
