NOTE: Some 2006 to 2010 estimates that are used in the comparisons may differ from previously published estimates due to updates (see Section 3.3.5 in Chapter 3 of the 2018 National Survey on Drug Use and Health: Methodological Summary and Definitions).
NOTE: Methodological limitations preclude the estimation of past year initiates for the overall prescription psychotherapeutics category and consequently the overall illicit drugs and illicit drugs other than marijuana categories.
1 Prescription psychotherapeutic subtypes were revised in 2016; one effect was the comparability of codeine products between 2015 and later years.
2 Illicit Drugs Other Than Marijuana excludes respondents who used only marijuana but includes those who used marijuana in addition to other illicit drugs.

NOTE: Respondents were classified as needing substance use treatment if they met the DSM-IV criteria for an illicit drug or alcohol use disorder or received treatment for illicit drug or alcohol use at a specialty facility (i.e., drug and alcohol rehabilitation facility [inpatient or outpatient], hospital [inpatient only], or mental health center).
NOTE: Perceived Need for Substance Use Treatment includes persons who did not receive but felt they needed illicit drug or alcohol use treatment, as well as persons who received treatment at a location other than a specialty facility but felt they needed additional treatment.
