Note: The 1995-96 NHSDA samples were not designed to produce fully representative California estimates. The size and coverage (approximately 95% of the California population) of the 1995-96 samples, however, were sufficient to provide reasonably accurate prevalence estimates for California. Although the sample weights associated with 1995-96 NHSDA respondents from California were not post-stratified to California population projections, analyses of the NHSDA data revealed this lack of post-stratification had little effect on estimated percentages of reported drug use. It may, however, have a significant effect on estimates of totals within certain subgroups.
*Low precision; no estimate reported.
-- Estimate not available.
aDifference between estimate and 1998 estimate is statistically significant at the .05 level.
