The replicability of cannabis use prevalence estimates in the United States.

ABSTRACT: Recent changes in cannabis policy in the United States have prompted increased interest in cannabis use estimates, and replicability of these estimates. Here, we compare prevalence estimates from two concurrent approaches: (1) standard social survey with audio computer-assisted self-interviews at respondent's home (ACASI-H), derived from the National Surveys on Drug Use and Health (NSDUH), and (2) standard health survey with ACASI assessment in a mobile health examination vehicle (ACASI-M), derived from National Health and Nutrition Examination Surveys (NHANES), 2005-2012, with essentially the same standardized items in cannabis modules. NHANES ACASI-M prevalence proportions for recently-active-cannabis-use are an estimated 130-140% larger than corresponding NSDUH ACASI-H estimates (p < 0.
