In California, it is legal to use cannabis for medical purposes.
Cannabis possession for personal use under 1 oz (28.5 grams) is punishable by a $100 fine. A person who possesses larger amounts of the drug may be sent to jail for 6 months and pay up to $500. Possession with intent to distribute is a felony, regardless of the amount of cannabis possessed, punished by 16-36 months of imprisonment.
Cultivating with intent to sell is considered a felony and may result in a sentence of up to 3 years of imprisonment in the county jail.
Legally, a person can only consume cannabis in a private residence.
Individuals 21 years or older with a medical marijuana ID card are allowed to possess up to 8 oz (0.5 pound) of usable marijuana. However, Senate Bill 420 allows patients to have a larger amount of marijuana when recommended by a doctor.
Qualifying patients may grow no more than 6 mature or 12 immature plants. Growing more plants is considered the reason for arrest and prosecution.
