In this paper we analyze data collected for the Arrestee Drug Abuse Monitoring (ADAM) program to compare the results of urinalysis with self-reported drug use, with particular attention to the time frame of self-reported use. We find that many respondents who test positive for a drug report the use of that drug, if not within the preceding 48 hours, then within the last week, month, or year. We examine this variation the temporal trajectory of self-reported use in terms of respondents' backgrounds, characteristics, and other variables.
