Who is affected
Individuals experiencing chronic substance use disorder who demonstrate an inability to control their actions or who manifest extremely abnormal behavior.
Requirements and enforcement
The bill authorizes courts, physicians, and psychiatrists to order involuntary admission to a receiving facility for treatment if the substance use creates a serious danger to the individual or others.
Costs and funding
The fiscal impact is currently unknown; the Office of Legislative Budget Assistant is awaiting information from the DHHS.
When it takes effect

What is still unknown
The total volume of new involuntary admissions and the subsequent cost to the state healthcare system remain completely unspecified.
