title: The validity of self-reported heroin use.
abstract: During a 2-year follow-up interview, 272 male veteran heroin addicts reported their recent heroin use and provided a urine sample. Eighty-four percent of those reporting no heroin use in the 3 months preceding the interview, and 78% of those declaring no use in the previous week had urines found negative for opiates. The subjective impressions of the interviewers were useful in predicting the veracity of the self-reports. Subjects who had been in longer-term treatment, especially therapeutic communities, were more likely to report heroin use truthfully.
