MI HB5580

Establishes the "Medical Marihuana Provisioning Center Regulation Act" to regulate medical marijuana dispensaries and related facilities in Michigan.

Provides immunity from criminal penalties, civil prosecution, search, seizure, and professional licensing sanctions for provisioning centers and safety compliance facilities that obtain municipal registration or license and comply with state and local law.

Prohibits provisioning centers from operating within 1,000 feet of schools, sharing office space with physicians, advertising on billboards/radio/television, or dispensing more than 2.5 ounces of usable marijuana per patient in any 10-day period.

Requires provisioning center employees to be at least 21 years old and have no felony convictions for drug offenses; mandates background checks and maintenance of confidential dispensing records for at least 90 days.

Authorizes municipalities to prohibit provisioning centers entirely, require licensing or registration with fees not exceeding regulatory costs, and impose additional local requirements; establishes civil fines of up to $5,000 for location violations and up to $1,000 for operational violations.
