This report presents State estimates for 20 measures of
substance use or mental health problems based on the 2002
National Survey on Drug Use and Health (NSDUH).1 Sponsored by
the Substance Abuse and Mental Health Administration (SAMHSA),
NSDUH is an ongoing survey of the civilian, noninstitutionalized
population of the United States aged 12 years old or older.
Approximately 68,000 persons were interviewed in 2002. State
estimates presented in this report are based on data collected
in 2002 and have been developed using a small area estimation
(SAE) procedure in which State-level NSDUH data are combined
with local-area county and census block group/tract-level data
from the State. These model-based estimates provide more precise
estimates of substance use at the State level than estimates
based solely on the sample. Beginning with the 1999 survey data,
SAMHSA produced estimates at the State level for a selected set
of variables (Office of Applied Studies [OAS], 2001b). These
variables included prevalence rate
