Patients and their caregivers are permitted to legally use, have, and grow cannabis for medical purposes. The law also protects not-for-profit collective and cooperative grow operations and allows primary caregivers to be reimbursed for the costs of their services.
To be a legal medical cannabis patient in California, you need a valid doctor's recommendation.
The state limits are: six mature or 12 immature cannabis plants plus eight ounces of dried cannabis per patient. Cities and counties can set limits that are higher than this limit, but cannot set lower limits. For a listing of known guidelines for localities across California, click here. Also, the doctor's recommendation can specify that you need an amount of medical cannabis that exceeds the limits, but only for your personal use.
