Legalization Timelines

1996: The Compassionate Use Act was passed after receiving 55.6% votes, which allowed the medical use of cannabis in California. This drug reform, also known as Proposition 215, provides legal protection to caregivers, physicians, and patients. Moreover, the new series of laws known as the Medical Cannabis Regulation and Safety Act (MCRSA) came into effect, which created a new regulatory and licensing framework for the medical cannabis industry in California. In November 2016, Proposition 64 was passed, allowing MCRSA to govern transportation, cultivation, testing, resale, and distribution.

2003: California Senate Bill 420, also known as the Medical Marijuana Program Act, was passed to establish an identification card system for patients of medical cannabis.

2009: The Marijuana Control, Regulation, and Education Act was passed, which removed penalties for the use, possession, and cultivation of marijuana for persons of age 21 or older.

2010: The voters in California rejected Proposition 19 by 53.5% votes, hence prohibiting legalized possession, cultivation, and possession of cannabis for adults aged 21 or older

2011: California decriminalized marijuana possession by reducing the charge from a misdemeanor to an infraction for possession of 28.5 grams of cannabis or less.

2016: Proposition 64 was passed by voters in California, which legalized the recreational use of cannabis. The bill allows the possession of 8 grams of concentrated cannabis by adults aged 21 years and older. Moreover, under the bill, an adult can cultivate six plants per residence and can purchase cannabis from licensed retailers.

2021: The California Cannabis Appellations Project (CAP) was implemented in California for the development of appellations of origin for marijuana products. The goal of CAP is to prevent misinterpretation about the origin of cannabis products and promote the regional cannabis business
