MI HB5681

Amends Michigan's controlled substances law to reclassify marihuana and synthetic cannabis as Schedule 2 controlled substances when manufactured, obtained, and used in compliance with a new pharmaceutical-grade cannabis program or the Michigan Medical Marihuana Act.

Establishes Article 8 to create a regulated system for cultivation, distribution, and sale of "pharmaceutical-grade cannabis" through state-licensed facilities with strict quality standards including testing for THC/CBD levels, microbial contamination, mycotoxins, and heavy metals.

Creates an "enhanced pharmaceutical-grade cannabis registration card" system allowing eligible patients with debilitating medical conditions to purchase pharmaceutical-grade cannabis from licensed facilities based on physician certification and compliance with specific usage restrictions.

Prohibits pharmaceutical-grade cannabis use while operating vehicles or in schools, correctional facilities, and public places; requires employers not accommodate workplace consumption but prevents retaliation against eligible patient employees exercising their rights under the program.

Establishes a pharmaceutical-grade cannabis fund through licensing and registration fees, with the Department of Public Health responsible for administering the program, conducting inspections, and enforcing compliance through license suspension or revocation.
