Authorizes outpatient substance use disorder treatment programs to make housing available under certain circumstances.

S 2340 authorizes licensed outpatient substance use disorder treatment programs to provide housing to patients needing both treatment and housing, under specific conditions. Programs must use separate contracts for housing (requiring patients to acknowledge repayment of subsidies), clarify that housing and treatment are not contingent on each other, and ensure housing complies with local zoning and safety laws. The bill maintains existing prohibitions against referral fees for treatment services, which remain punishable by law. This directly affects treatment programs and patients seeking integrated support for substance use disorder and housing needs.
