The gap between what people admit about their behavior and what is actually true has plagued social scientists and survey methodologists for decades. This gap would not matter if it did not play an important role in estimation of the extent of the consumption of illegal drugs and/or changing trends in illegal use, both data critical for developing public policy and determining the effects of intervention programming and policy changes. The Arrestee Drug Abuse Monitoring (ADAM) survey matches anonymous self-reported interview information to a urine test for nine drugs in a probability-based sample of adult male arrestees conducted within 48 hr of their arrest. Using data from 2000-2003 and 2007-2011 collected in 10 U.S. counties, this article looks at how the gap between the truth and reality in self-report varies by the drug reported, by the region of the country, over time, and by characteristics of the user, and discusses the relevance of these findings to policy.
