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 2019 National Survey on Drug Use and Health: Methodological Summary and Definitions).

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 2019 National Survey on Drug Use and Health: Methodological Summary and Definitions).
1 Illicit Drug Use in Lifetime includes the misuse of prescription psychotherapeutics even though those estimates are not reported due to potential underreporting in lifetime prescription psychotherapeutics estimates.
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: 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 2019 National Survey on Drug Use and Health: Methodological Summary and Definitions).
1 Prescription psychotherapeutic subtypes were revised in 2016; one effect was the comparability of codeine products between 2015 and 2016.
2 Includes only respondents who smoked cigarettes on each of the past 30 days.
3 Estimates of binge alcohol use that are used in the comparisons include use by those who were heavy alcohol users.
4 Respondents with missing data for number of cigarettes smoked per day were excluded from the analysis.

NOTE: Respondents were classified as needing the specific substance use treatment if they met the DSM-IV criteria for the specific illicit drug or alcohol use disorder or received treatment for the specific 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).
1 Estimates that are used in the comparisons include persons who received treatment specifically for illicit drugs or alcohol, as well as persons who received treatment for unspecified substance(s).

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.
