Medical Marijuana Identification Cards

In 1996, California voters passed Proposition 215, also known as the Compassionate Use Act. The Act made the medical use of marijuana legal in California. However, it did not provide an effective way for law enforcement to properly identify patients who were legally protected by the Act. As a result Of Senate Bill 420, the Medical Marijuana Program (MMP) was established by the California Department of Health Services in 2004. The MMP allows qualified patients to apply for and receive Medical Marijuana Identification Cards for themselves and their primary caregiver though their county of residence

Napa County residents with a recommendation from a physician for medical cannabis and their caretakers are eligible for this program.
