Cannabis Dos and Don'ts for California Visitors

Last verified: March 2026

The Dos

Do Buy from Licensed Dispensaries Only

This is the single most important rule. California's illicit market is massive — unlicensed shops and delivery services still outnumber licensed ones in many areas. Unlicensed products are not tested for pesticides, heavy metals, mold, or accurate potency. In 2025 alone, the DCC issued 34 recalls covering 444 products from licensed dispensaries — imagine what slips through in the unregulated market.

How to verify: Use the DCC's "Real CA Cannabis" lookup tool at cannabis.ca.gov. Every licensed dispensary has a DCC license number displayed on its premises. If you cannot find the license number, walk out.

Do Bring a Valid 21+ ID

Every dispensary checks ID at the door — no exceptions. Accepted forms: U.S. driver's license, state ID card, U.S. passport or passport card, military ID, or foreign passport. The ID must be valid and unexpired. Expired IDs are rejected. If you are visiting from another country, bring your passport.

Do Tip Your Budtender

Tipping at dispensaries follows the same norms as tipping a bartender. A standard tip is $3–$5 per transaction. For delivery orders, tip 15–20% as you would a food delivery driver. Budtenders earn modest wages and often provide extensive, personalized guidance — especially to first-time buyers.

Do Start Low and Go Slow

California produces some of the most potent cannabis in the world. If you are new to cannabis or have low tolerance:

• Flower: Take one or two puffs and wait 15 minutes before more
• Edibles: Start with 2.5–5mg of THC. Wait at least 90 minutes before taking more. Edible onset can take 30–90 minutes, and the effect lasts 4–8 hours. The most common mistake visitors make is eating a second dose before the first kicks in
• Concentrates: High-potency products (70–90%+ THC). Not recommended for beginners

Do Keep Cannabis Secured in Your Vehicle

When transporting cannabis in a car, keep it in a sealed container in the trunk or in a locked glove compartment. Open containers of cannabis in the passenger area of a vehicle carry a fine of up to $100, similar to open container alcohol laws.

The Don'ts

Don't Consume in Public

Public cannabis consumption is illegal statewide. This includes sidewalks, parks, beaches, restaurant patios, bar areas, and anywhere within 1,000 feet of a school, daycare, or youth center while children are present. The fine is $100 for a first offense, escalating to $250 for repeat violations. Some cities impose higher local fines.

Legal consumption locations: private residences (with landlord permission), licensed consumption lounges, and designated areas at licensed cannabis events.

Don't Drive Impaired

California prosecutes cannabis DUI under Vehicle Code 23152(f). There is no per se THC blood level threshold (unlike Colorado's 5ng/ml rule), but impairment itself is what is prosecuted. Law enforcement uses field sobriety tests and Drug Recognition Expert evaluations. A first-offense cannabis DUI carries:

• Up to 6 months in jail
• $390–$1,000 in fines
• 3–5 year probation
• License suspension
• DUI school

Use rideshare, taxi, or a designated driver. Every consumption lounge posts rideshare information for this reason.

Don't Take Cannabis to National Parks or Federal Land

Cannabis possession on federal land is a federal misdemeanor regardless of state law. California is home to some of the most visited national parks in the country:

• Yosemite National Park
• Joshua Tree National Park
• Death Valley National Park
• Sequoia & Kings Canyon National Parks
• Redwood National & State Parks (the national park portions)
• Channel Islands National Park
• Point Reyes National Seashore

National forests (Angeles, Los Padres, Shasta-Trinity, Tahoe, etc.), BLM land, and military installations are also federal territory. Leave cannabis behind before entering any federal land.

Don't Fly with Cannabis

Airports and airspace are under federal jurisdiction. TSA officers do not specifically search for cannabis, but if they discover it during routine screening, they are required to refer the matter to local law enforcement. In practice:

• LAX: Installed cannabis "amnesty boxes" near security checkpoints. If you forgot to leave your cannabis behind, you can dispose of it before entering federal security. LAXPD has stated they will not arrest travelers for amounts within California's legal limits
• SFO & SAN: Airport police have similarly permissive stances on state-legal amounts, but this is discretionary — not a guarantee
• Smaller airports: Policies vary. Do not assume

The safest approach: do not bring cannabis to the airport. Consume or dispose of your remaining products before heading to your flight.

Don't Cross State Lines

Transporting cannabis across state lines is a federal crime under the Controlled Substances Act, even between two states where cannabis is legal. This applies to:

• Driving to Nevada, Oregon, or Arizona with California cannabis
• Mailing or shipping cannabis out of state
• Amtrak trains crossing state borders
• Interstate highways near borders (I-15 to Nevada, I-5 to Oregon)

Don't Assume Every City Has Dispensaries

Approximately 57% of California's jurisdictions ban retail cannabis dispensaries. Many popular tourist destinations — including much of Orange County, large parts of the Central Valley, and numerous suburban cities throughout the state — have no legal dispensaries. Check dispensary availability before arriving at your destination, or plan to use delivery services, which are legal statewide.
