California Medical Marijuana Program



The California Department of Public Health’s Medical Marijuana Program (MMP) was specifically established to create a State-authorized medical marijuana identification card (MMIC), along with a registry database for verification of qualified patients and their primary caregivers. Participation by patients and primary caregivers in this identification card program is voluntary. The MMP Web-based registry allows law enforcement and the public to verify the validity of a qualified patient or primary caregiver's MMIC as authorization to possess, grow, transport, and/or use medical marijuana within California. The verification website is available on the internet at www.calmmp.ca.gov



NOTE: The California Department of Public Health’s MMP does not have jurisdiction over medical marijuana cooperatives, dispensaries, or collectives. For questions related to these areas, please contact your local city or county business licensing office.
