Illicit Drug Use, Past 30 Days (NSDUH)

Data Source: National Survey on Drug Use and Health, SAMHSA

Background: 

The National Survey on Drug Use and Health (NSDUH) measures:

  • use of illegal drugs, prescription drugs, alcohol, and tobacco
  • mental disorders, treatment, and co-occurring substance use and mental disorders

The data provides estimates of substance use and mental illness at the national, state, and sub-state levels. NSDUH data also help to identify the extent of substance use and mental illness among different sub-groups, estimate trends over time, and determine the need for treatment services.

Population Captured:

NSDUH collects data through face-to-face interviews with residents of households who are:

  • US civilians
  • older than 12 years old (in some instances where noted data measures individuals 12-20)
  • not institutionalized

This includes people who live in non-institutional group residences, such as shelters, rooming houses, or dormitories, as well as civilians living on military bases. The survey does not include people who are homeless or do not use shelters, military personnel on active duty, or residents of institutional group quarters, such as jails and hospitals.
