Using data from 2 waves of the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC), Hasin and colleagues1 reported that the past-year prevalence of marijuana use in the United States has more than doubled in a decade (2002-2003 to 2012-2013), along with a comparable increase in the past-year prevalence of marijuana use disorder as defined by the DSM-IV. Because a previous report documented large discrepancies between drug use estimates from the NESARC and those provided by the National Survey on Drug Use and Health (NSDUH),2 we sought to directly compare prevalence estimates and trends in marijuana use and marijuana use disorder from the NSDUH those from the NESARC.
