Involuntary treatment of substance use disorder.

Allows an individual's spouse, legal guardian, friend, relative, or medical service provider to petition a court for involuntary substance use disorder treatment. Requires a petition to include certain information and allows a court to dismiss a petition, without prejudice, if it does not contain the required information. Requires the court to appoint a public defender if the individual subject to a petition seeking involuntary substance use disorder treatment is not represented by an attorney. Requires a court to order the individual to be evaluated by a medical provider if the court finds that: (1) the individual has a substance use disorder; (2) because of the individual's substance use disorder, the individual is experiencing impaired judgment and is unable to independently maintain the individual's activities of daily living or is a danger to self or others; and (3) the individual refuses to voluntarily participate in substance use disorder treatment. Allows a court to order a local law enforcement agency to consider whether an individual meets the criteria for emergency detention under certain circumstances. Requires a medical provider who completes an evaluation concerning an individual's need for substance use disorder treatment to submit the evaluation to the court. Specifies that after receiving an evaluation from a medical provider, the court may dismiss the petition or set a hearing for further evidence to be presented about the individual's need for substance use disorder treatment. Requires a court to order involuntary outpatient substance use disorder treatment for a period, not to exceed 90 days, if medical evidence supports that the individual requires immediate treatment for a substance use disorder and the individual has refused treatment.
