The NSDUH questionnaire underwent a partial redesign in 2015. Due to the potential breaks in comparability, many estimates from prior years are not comparable due to methodological changes. These changes led to potential breaks in the comparability of estimates from prior years. These include measures of smokeless tobacco, overall illicit drug use, use of hallucinogens, MDMA (Ecstasy), inhalants, methamphetamine, and misuse of psychotherapeutics. For more detailed information on these revisions, see the 2016 National Survey on Drug Use and Health: Methodological Summary and Definitions.
