Comparison between self-report and hair analysis of illicit drug use in a community sample of middle-aged men.

Discrepancies between biological assays and self-report of illicit drug use could undermine epidemiological research findings. Two objectives of the present study are to examine the degree of agreement between self-reported illicit drug use and hair analysis in a community sample of middle-aged men, and to identify factors that may predict discrepancies between self-report and hair testing. Male participants followed since 1972 were interviewed about substance use, and hair samples were analyzed for marijuana, cocaine, opiates, phencyclidine (PCP) and methamphetamine using radioimmunoassay and gas chromatography-mass spectrometry (GC-MS) techniques.

Asians in the United States: substance dependence and use of substance-dependence treatment.

Clinicians have often observed that Asians are unlikely to utilize substance-dependence treatment services but few have reported empirical data examining this phenomenon. This study used data from the National Household Survey on Drug Abuse, 2000-2002, and tested whether Asians in the United States have relatively low rates of drug and alcohol dependence and whether substance-dependent Asians use treatment services less than Caucasians. Subsequent analyses were undertaken to identify factors that explained these racial differences.

Substance use and abuse by Asian Americans and Pacific Islanders: preliminary results from four national epidemiologic studies.

Objective: The authors analyzed four recent large national surveys to assess the degree of use and abuse of a wide range of psychoactive substances across subgroups of Asian Americans and Pacific Islanders (AAPIs) and in comparison with whites.

Method: The surveys analyzed were the 1999 National Household Survey on Drug Abuse, the 1992 National Longitudinal Alcohol Epidemiologic Survey, and the 1995 National Longitudinal Study of Adolescent Health In-School and In-Home surveys. The AAPI sample sizes varied from 900 to more than 4,500 across the four surveys.
