Other: The National Substance Use and Mental Health Services Survey (N-SUMHSS) is an annual, voluntary survey conducted by the Substance Abuse and Mental Health Services Administration (SAMHSA). It aims to collect comprehensive data on substance use and mental health treatment facilities across the United States, including U.S. territories and the District of Columbia. The survey provides a detailed "snapshot" of the services offered, facility characteristics, and client demographics as of a specific reference date. The dataset includes annual data from 2021 through 2023, with each year's data accompanied by a codebook and questionnaire detailing the variables and methodology used.
