The Two Propositions
California's cannabis legal framework rests on two landmark ballot measures, both rooted in San Francisco:
Proposition 215 (1996) — Medical Cannabis
Proposition 215, the Compassionate Use Act, passed on November 5, 1996 with 55.6% of the vote, making California the first state in the nation to legalize medical cannabis. The law was co-authored by San Francisco's Dennis Peron and Brownie Mary (Mary Jane Rathbun), and grew directly from the AIDS crisis and the Cannabis Buyers Club.
Prop 215 allowed patients with a doctor's recommendation to possess and cultivate cannabis for medical use. It was intentionally broad — Peron wanted it that way — and its passage triggered a cascade of medical cannabis laws across the country.
Proposition 64 (2016) — Recreational Cannabis
Proposition 64, the Adult Use of Marijuana Act (AUMA), passed in November 2016 and took effect on January 1, 2018. It legalized recreational cannabis for adults 21 and older, established the regulatory framework, and created the state licensing system.
Key provisions of Prop 64:
- Adults 21+ may possess up to 1 ounce (28.5g) of flower or 8 grams of concentrate
- Adults may cultivate up to 6 plants per residence (not per person)
- Established a state excise tax on cannabis sales
- Created an expungement process for prior cannabis convictions
- Allowed local jurisdictions to regulate or ban cannabis businesses
The Department of Cannabis Control (DCC)
The Department of Cannabis Control (DCC) was created in July 2021 by consolidating three separate agencies that had been regulating different aspects of the cannabis industry. The DCC is the single state agency responsible for:
- Licensing all cannabis businesses (cultivation, manufacturing, distribution, retail, testing, delivery)
- Enforcement and compliance
- Track-and-trace (seed-to-sale tracking)
- Consumer protection and product safety
As of February 2025, the DCC has issued 8,514 active licenses across all categories statewide.

Possession and Purchase Limits
| Category | Limit |
|---|---|
| Flower (on person) | 1 ounce (28.5 grams) |
| Concentrates (on person) | 8 grams |
| Home cultivation | 6 plants per residence |
| Minimum age | 21 (recreational) / 18 (medical with recommendation) |
| Residency requirement | None — visitors welcome |
Tax Structure
California's cannabis tax structure has been revised multiple times in response to the industry's financial crisis:
| Tax Type | Rate |
|---|---|
| State excise tax | 15% (frozen through mid-2028 via AB 564) |
| State/local sales tax | ~8.6% |
| SF local cannabis tax | 0% (suspended through 2035) |
| Effective Total (SF) | ~23–25% |
| Comparison: Los Angeles | ~38–44% (with 10% local tax) |
SF is the only major CA city with zero local cannabis tax. Suspended through December 31, 2035.
Cultivation Tax: Eliminated (2022)
California eliminated the cultivation tax entirely in 2022, removing a per-ounce tax on harvested cannabis that had been adding costs throughout the supply chain. This was an acknowledgment that the tax burden was unsustainable.
Excise Tax: Frozen at 15% (AB 564)
AB 564 froze the state excise tax at 15% through mid-2028, preventing the scheduled increases that would have pushed the rate higher. Without this freeze, the excise tax would have been adjusted upward based on a markup formula that could have exceeded 20%.
Consumption and Public Use
California law prohibits cannabis consumption in public places, with specific rules varying by jurisdiction:
- Private property: Legal with the property owner's permission
- Public places: Illegal everywhere tobacco is banned. In San Francisco, the fine is $250. Cannabis cannot be consumed within 15 feet of doors, windows, and vents.
- Vehicles: Illegal to consume cannabis in a vehicle, whether driving or as a passenger. Open containers must be in the trunk or a sealed, non-accessible area.
- Federal land: Cannabis is illegal on all federal property, including national parks, military bases, and federal buildings. In San Francisco, this includes the Presidio, Alcatraz, Ocean Beach (NPS), Aquatic Park, and the Marin Headlands.
AB 1775: Consumption Lounges (January 2025)
AB 1775, effective January 2025, transformed California's consumption lounge landscape. Previously, lounges could sell cannabis for on-site consumption but were prohibited from offering food, beverages, or hosting events. AB 1775 unlocked:
- Non-cannabis food and beverages (non-alcoholic) can be sold and served
- Ticketed performances and events — live music, comedy, drag shows, trivia nights
- No alcohol can be served or consumed on premises
For San Francisco, which already had more consumption lounges than any other city in America, AB 1775 was transformative. Lounges like Barbary Coast, Moe Greens, and Mission Cannabis Club can now function as full social venues — not just smoking rooms. See our Lounge Guide for details.
AB 1775 turned SF's lounges from smoking rooms into social venues. Barbary Coast hosts comedy and trivia nights with food. Moe Greens runs weekly jazz, comedy, trivia, and bingo. Expect the lounge scene to expand rapidly as businesses adapt to the new rules.
AB 2188: Employment Protections (January 2024)
AB 2188, effective January 1, 2024, prohibits most California employers from discriminating against employees or applicants based on off-duty cannabis use. Specifically:
- Employers cannot penalize employees for cannabis use outside of work
- Pre-employment drug testing for cannabis is restricted (employers cannot use tests that detect non-psychoactive metabolites)
- Exceptions: federal contractors, employees in safety-sensitive positions, and roles requiring federal security clearance
- Does not permit impairment at work or on-the-job cannabis use
AB 2188 is one of the strongest cannabis employment protection laws in the country and is particularly significant in the Bay Area's tech-heavy economy, where drug testing policies had already been relaxed informally for years.
DUI and Driving
California treats cannabis DUI with the same severity as alcohol DUI:
- Fines of approximately $10,000
- 10-month license suspension
- Possible jail time
- No per-se THC limit (unlike blood alcohol); impairment is assessed by officers and Drug Recognition Experts
Use Muni, BART, Uber, or Lyft. San Francisco has excellent public transit. There is no reason to drive after consuming, and the penalties are severe.
Home Cultivation
Adults 21+ may grow up to 6 cannabis plants per residence (not per person). The plants must be in a locked space not visible from a public place. Local jurisdictions can impose reasonable regulations on indoor cultivation but cannot ban it. Outdoor cultivation can be restricted or banned by local ordinance.
