Note: Data in this
table are preliminary composite estimates derived from the National
Household Survey on Drug Abuse (NHSDA) and the Arrestee Drug
Abuse Monitoring (ADAM) program (see W. Rhodes,"Synthetic Estimation
Applied to the Prevalence of Drug Use," Journal of Drug Issues
23(2):297�321, 1993, for a detailed description of the methodology).
The NHSDA was not administered in 1989. Estimates for 1989 are the average
for 1988 and 1990.
*Estimates for 2000
are projections.
1"Occasional"
is defined as using drugs fewer than 10 days per month.
2"Chronic"
