The NSDUH questionnaire underwent a partial redesign in 2015. Due to the potential breaks in comparability, many estimates from prior years have been noted in the table as not comparable due to methodological changes. These changes led to potential breaks in the comparability of 2015 estimates with 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 Sections B and C of the 2015 National Survey on Drug Use and Health: Methodological Summary and Definitions.
