Proposition 64, formally titled the Control, Regulate and Tax Adult Use of Marijuana Act, is a California voter initiative that legalized cannabis for recreational use. Passed on November 8, 2016, with 57% voter approval, the measure became law on November 9, 2016, and enabled recreational cannabis sales to begin in California by January 2018. The legislation authorizes individuals over age 21 to possess, cultivate, and purchase marijuana while establishing a comprehensive regulatory framework for commercial cannabis activities.
The measure fundamentally altered California law by legalizing the possession, cultivation, and sale of marijuana for adults. According to the California Legislative Analyst's Office, Proposition 64 permits adults over 21 to possess up to 28.5 grams of marijuana or 8 grams of concentrated cannabis. The initiative also allows cultivation of up to six living marijuana plants per residence for personal use, with plants and excess marijuana required to be stored in locked spaces not visible from public areas.
In addition to legalization, Proposition 64 established significant criminal justice reforms. The act reduces penalties for most marijuana-related offenses, reclassifying many felonies as misdemeanors and certain misdemeanors as infractions. These provisions apply to both adults and juveniles, though different penalty structures exist based on age groups. The measure expressly provides for resentencing and redesignation of prior convictions, allowing individuals previously convicted of marijuana felonies to petition courts for reclassification to misdemeanors.
The taxation structure under Proposition 64 includes a 15% excise tax on gross receipts of retail sales, alongside cultivation taxes of $9.25 per dry-weight ounce for marijuana flowers and $2.75 per dry-weight ounce for leaves. Revenue generated flows into the California Marijuana Tax Fund, with 60% allocated to youth programs, 20% to environmental damage cleanup, and 20% to public safety initiatives.
The regulatory apparatus created by Proposition 64 includes the Bureau of Marijuana Control, which oversees licensing and regulation of commercial cannabis operations. Multiple state agencies participate in regulation, including the California Department of Food and Agriculture for cultivation licensing, the California Department of Public Health for manufacturing oversight, and environmental agencies for cultivation impact management. While the act transformed recreational marijuana laws, it preserved existing rights for medical marijuana patients under Proposition 215, the Compassionate Use Act of 1996.
The Adult Use of Marijuana Act permits adults aged 21 and older to possess up to 28.5 grams of non-concentrated cannabis and 8 grams of concentrated cannabis. These possession limits apply to purchases from licensed retailers, with each adult permitted to acquire these amounts per day from individual retail locations. Additionally, the act allows adults to give away up to one ounce of marijuana to other adults without any compensation, though sales for profit require proper state licensing.
Adults meeting the age requirement may legally possess, process, transport, purchase, and obtain cannabis within specified limits under Health and Safety Code section 11362.1. The statute distinguishes between non-concentrated cannabis, limited to 28.5 grams, and concentrated cannabis products, capped at 8 grams including concentrates contained within cannabis products. Possession and transportation of these amounts does not constitute a violation of state or local law, provided the individual remains within residential or authorized consumption areas.
Personal cultivation authorizes adults to plant, cultivate, harvest, dry, and process up to six living cannabis plants per residence. This limit applies to each private residence rather than per individual, meaning multiple residents sharing a dwelling collectively may not exceed six plants. Cultivation must comply with specific location requirements:
Licensed businesses exclusively may sell cannabis for recreational purposes, with licensing authority vested in the state Bureau of Marijuana Control. Retailers must obtain licenses from the Department of Cannabis Control, which enforces strict rules preventing sales to minors and ensuring product testing accuracy. Cannabis packaging requires disclosure of net weight, origin, product age, type, milligram amounts of THC and CBD per serving, and pesticide use during cultivation. Local governments retain authority to completely ban marijuana-related commercial businesses within their jurisdictions, resulting in retail cannabis prohibition in approximately 80% of California's municipalities.
Prop 64 establishes a comprehensive licensing and regulatory framework administered through multiple state agencies. The Bureau of Marijuana Control, created under the legislation, began issuing licenses on January 1, 2018. Following subsequent reorganization, the Department of Cannabis Control assumed responsibility for licensing and regulation of all cannabis operations in California. The regulatory structure parallels the framework established under the Medical Cannabis Regulation and Safety Act of 2015, merging both medical and recreational oversight into a unified system.
California operates a dual licensing system for cannabis businesses, requiring operators to secure permits from both local jurisdictions and state agencies. Applicants must first obtain approval from their local municipality before receiving state licensure. State licensing authorities cannot issue licenses to commercial cannabis businesses if operation would violate local ordinances in the jurisdiction where the business would operate. Consequently, businesses must navigate two distinct sets of regulations, with local requirements often exceeding state standards in stringency.
The licensing framework encompasses multiple categories of commercial activity, including cultivation, manufacturing and processing, distribution, retail sales, and testing laboratories. Application fees total $1,000, while license fees range from $2,500 to $96,000 depending on projected annual revenue. The licensing process requires background checks, fingerprinting, proof of financial responsibility, and detailed facility and security plans. Local approval typically involves multiple departments, including planning, zoning, police, fire, and building departments.
Compliance requirements extend beyond initial licensing. State-approved laboratories must conduct mandatory testing of all cannabis products for pesticides, microbial impurities, heavy metals, and residual solvents. Testing protocols also establish potency levels and cannabinoid profiles for consumer information. Packaging must be child-resistant and tamper-evident, with labels disclosing product name and type, THC and CBD percentages, net weight or volume, batch number, expiration date, and ingredients. California contracted with METRC to implement a track-and-trace system for monitoring all cannabis products throughout the supply chain. Marketing activities face restrictions prohibiting advertisements near youth facilities, use of cartoon imagery, and false health claims.
Retroactive relief provisions constitute a central component of the legislation, enabling individuals with prior marijuana convictions to seek modification or elimination of their criminal records. The measure permits reclassification of felony convictions to misdemeanors and misdemeanor convictions to infractions, while certain qualifying offenses may be dismissed and sealed entirely. Eligibility depends on the individual's age at the time of offense, the specific marijuana-related crime, and the absence of disqualifying exceptions.
Individuals serving sentences for activities legalized or subject to reduced penalties under the statute qualify for resentencing through petition to the sentencing court. Courts may recall and resentence eligible felony convictions to misdemeanor status, with maximum sentences not exceeding 180 days in county jail for reclassified offenses. The petition process requires completion of Form CR-400 for each case separately, submitted to the Superior Court where the conviction occurred, with service upon the prosecuting agency. No filing fee applies to these petitions. Courts retain discretion to deny resentencing if the individual poses a likelihood of committing severe crimes, though this determination requires specific judicial findings.
Convictions under Health and Safety Code sections 11357 (possession), 11358 (cultivation), 11359 (possession for sale), and 11360 (transportation) qualify for redesignation. When convictions are reclassified, they become misdemeanors or infractions "for all purposes," eliminating the requirement to disclose prior felony status. Furthermore, resentenced individuals currently incarcerated become subject to community supervision for up to one year following release, unless a court removes that requirement.
State agencies must automatically destroy records of arrest and conviction from January 1, 1976 or later for possession offenses under Health and Safety Code sections 11357 and 11360(b), plus juvenile adjudications for marijuana-related offenses excluding synthetic marijuana under section 11357.5. Agencies destroy these records two years after conviction or two years after arrest if no conviction occurred. Offenses occurring on K-12 school grounds remain on record until the individual turns 18, at which point destruction occurs. Complete dismissal and sealing applies when the marijuana offense is no longer criminalized, rendering arrest records, court records, and Department of Justice records inaccessible.
Local jurisdictions retain extensive regulatory authority over cannabis operations within their boundaries under the measure's framework. Cities and counties possess the power to completely ban all cannabis businesses, including dispensaries, cultivation facilities, manufacturing operations, and delivery services. However, municipalities cannot entirely prohibit personal cultivation of up to six plants by adults in private residences, though they may impose reasonable restrictions on cultivation practices. Furthermore, local governments maintain authority to prohibit outdoor personal cannabis cultivation while permitting indoor cultivation.
The dual licensing structure requires cannabis businesses to obtain permits from both local jurisdictions and state agencies before commencing operations. State licensing authorities cannot issue licenses if business operation violates local ordinances in the proposed jurisdiction. Consequently, local governments exercise final regulatory authority over cannabis industry presence within their communities. As of December 2023, 56 percent of California jurisdictions prohibited all types of cannabis businesses from operating within their boundaries.
Local governments establish zoning requirements, permitting processes, and fee structures independently. Municipalities may limit the number of permits issued, determine allowable business types, and designate approved locations for cannabis operations. They also decide permits for businesses offering on-site consumption. However, jurisdictions that ban all cannabis commercial activity forfeit tax revenue generated by the measure.
The Board of State and Community Corrections released USD 125 million in grant funding to support local governments addressing public health and safety impacts associated with cannabis legalization, bringing statewide funding to nearly USD 250 million. Eligible applicants must be local governments that have not banned both indoor and outdoor commercial cultivation or retail sales. Grant categories include youth development, public health, public safety, and environmental impacts.
Jurisdictions adopting more restrictive cannabis policies than their surrounding counties create regulatory conflicts, particularly regarding delivery services traversing multiple jurisdictions with varying restrictions.
The measure implements a dual tax structure on cannabis transactions through the Cannabis Tax Fund. Initially, the legislation established a 15% excise tax on retail gross receipts alongside cultivation taxes of $9.65 per ounce of dried flowers, $2.87 per ounce of dried leaves, and $1.35 per ounce of fresh plants. The California Department of Tax and Fee Administration adjusts cultivation tax rates annually for inflation. Following passage of AB-195 in 2022, the cultivation tax was eliminated, with the excise tax serving as the primary state revenue mechanism.
The 15% excise tax applies to all retail cannabis purchases, generating the majority of state cannabis revenue. Cannabis businesses additionally pay standard sales and use taxes ranging from 7.25% to 10.5% across jurisdictions, with a statewide average of 8.6%. Local governments may impose additional taxes on cannabis operations within their boundaries.
Cannabis Tax Fund proceeds follow a three-tier distribution structure. Tier 1 reimburses state agencies for regulatory and administrative costs not covered by license fees. Tier 2 allocates $10 million to university research, $50 million to community reinvestment grants, $3 million to the California Highway Patrol for impaired driving protocols, and $2 million to UC San Diego for medicinal cannabis research. Tier 3 distributes remaining revenues as follows: 60% to youth education, prevention, and treatment programs; 20% to environmental restoration; and 20% to law enforcement and public safety initiatives.
