NOTE:The population distributions for the 1993 through 1996 NHSDAs are post-stratified to population projections of totals based on the 1990 decennial census. NHSDAs from 1985 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 a significant effect on estimates of number of drug users in some subpopulation groups.

¹Estimates for 1985 through 1993 may differ from estimates for these survey years that were published in other NHSDA reports. The estimates shown here for 1985 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. Because of the methodology used to adjust the 1985 through 1993 estimates, some logical inconsistency may exist between estimates for a given drug within the same survey year. These inconsistencies tend to be small, rare, and not statistically significant.

^aDifference between estimate and 1996 estimate is statistically significant at the .05 level.

^bDifference between estimate and 1996 estimate is statistically significant at the .01 level.
