Buying cannabis in Washington as a visitor: ID, limits and where you can use it
Yes. Anyone 21 or older can buy at a licensed Washington store; residency isn't required. Bring an unexpired government ID, like any state's license or a passport. Each purchase has state limits. You can't use cannabis in public or in a car, or take it out of Washington.
Anyone 21 or older can buy, and you don't have to live in Washington. (WAC 314-55-079(1); WSLCB) You can't buy for anyone under 21, and you can't sell what you buy.
Which IDs work (WAC 314-55-150)
Bring the physical, unexpired card. Any of these works:
A driver's license, instruction permit or ID card from any U.S. state, a Canadian province, a U.S. territory or D.C.
A passport, a passport card, a Global Entry card, a NEXUS card or a Permanent Resident card
A U.S. armed forces ID (active, reserve, retired or dependent)
A U.S. Merchant Marine ID
A tribal enrollment card from a federally recognized tribe in Washington, if it has security features comparable to a Washington license
Expired IDs aren't accepted. (WAC 314-55-150(2)) We don't take photos of IDs either, and phone or digital IDs aren't on the state's list, so bring the card itself.
How much you can buy at once (WAC 314-55-095; RCW 69.50.360)
Product
Most in a single purchase
Flower (usable cannabis)
1 ounce
Solid edibles
16 ounces
Cannabis drinks and other liquids
72 ounces, or 200 mg THC if the product comes in units of 4 mg THC or less
Concentrates and vape oil
7 grams
Other infused products
10 units
Our budtenders check every purchase against these limits. Each limit applies on its own, so one purchase can include, for example, an ounce of flower and 7 grams of concentrate. These are also the amounts you're allowed to carry, so we can't sell you more on a second purchase if it would put you over. Mixing the two kinds of cannabis drinks in one cart? Ask the budtender how it counts. (WAC 314-55-095(1)(d); RCW 69.50.360(3); RCW 69.50.4013(3))
Where you can't use it
In public. That means sidewalks, parks, beaches, transit (stations and trains), and store parking lots. Opening a package or using cannabis in public view is a civil infraction. (RCW 69.50.445)
In the car: An unopened, sealed package can go anywhere in the car. Once a package has been opened, it has to ride in the trunk, or, if there's no trunk, somewhere nobody in the car can reach. The glove box and other storage compartments count as within reach. Using cannabis in a car on a public road is against the law, for passengers too. (RCW 46.61.745) Driving with a blood THC level of 5.00 ng/mL or more within two hours of driving is a DUI, and you can be convicted on other evidence too. (RCW 46.61.502)
On a boat you're operating. Operating a vessel under the influence of cannabis is a gross misdemeanor. (RCW 79A.60.040) Using cannabis anywhere the public can see you is a civil infraction, on the water too. (RCW 69.50.445)
On federal property, including national parks such as Mount Rainier and Olympic. (WSLCB)
On a plane, or anywhere outside Washington. (WSLCB)
Where you can
On private property, out of public view, with the owner's permission. Hotels and short-term rentals set their own rules, and many don't allow smoking, so check with yours first.
Sharing
You can give cannabis to another adult 21 or older if no money or anything else changes hands. In one 24-hour period, a gift can be up to half an ounce of flower, 8 ounces of solid edibles, 36 ounces of liquid products (or 100 mg THC if the product comes in units of 4 mg THC or less), or 3.5 grams of concentrate. Either keep it in its original store packaging or hand it over in private, out of public view. Never give cannabis to anyone under 21. (RCW 69.50.4013(4))
Taking it home
You can't. It's illegal to take cannabis out of Washington, including into Oregon, Idaho or Canada, and it's illegal to fly with it. (WSLCB)
Buying at Seattle Cannabis Co.
We're at 7266 Rainier Ave S, open 8 AM to 11 PM every day, a short walk from Othello light rail. We're cash only, with an ATM in the lobby. Order ahead on the live menu and pay cash at the counter when you pick it up. Washington doesn't allow cannabis stores to deliver. (WAC 314-55-079(5))
Not in our parking lot, either. No one opens or uses cannabis anywhere on our property, and we will ask you to leave.
