Two programs, one supply chain
Washington has two parallel cannabis programs administered by two different agencies. The recreational program — created by Initiative 502 in 2012 — is run by the Liquor and Cannabis Board (LCB). The medical program — older, restructured under SB 5052 in 2015 — is run by the Department of Health (DOH).
Both programs draw from the same regulated supply chain. The flower, edibles, and concentrates on a recreational shelf and a medical shelf come from the same licensed producers and processors, tested by the same state-certified labs, under the same WAC 314-55 framework. What differs is who can buy, what counter they buy at, what tax applies, and what dose ceilings are in play.
The recreational lane
Anyone 21 or over with valid government ID can shop at any licensed Washington recreational dispensary. There’s no application, no card, no doctor’s note. The product is taxed at the full 37% state excise plus state and local sales tax. Daily purchase limits apply: 1 oz of flower, 16 oz of infused-edible solid, 72 oz of infused-edible liquid, 7 g of concentrate. Edibles are capped at 100 mg total THC per package and 10 mg per piece.
This is the lane most Washington adults use. It’s broad, accessible, and consistent across the state.
The medical lane
The medical lane requires a qualifying patient designation. The process:
1. A qualifying patient sees a Washington-licensed health-care provider (MD, DO, PA, ND, ARNP). 2. The provider documents that the patient has a qualifying condition listed in RCW 69.51A.010 (intractable pain, cancer, MS, glaucoma, several others) and confirms that the patient may benefit from medical cannabis use. 3. The provider issues a medical cannabis authorization. 4. The patient enters their authorization into the state’s medical cannabis database via a medically endorsed dispensary, and the DOH issues a recognition card.
A recognition card holder can:
- Buy cannabis at a medically endorsed dispensary (most, but not all, licensed stores have the medical endorsement) tax-exempt from state and local sales tax. The 37% excise still applies.
- Access higher possession limits: 3 oz flower, 48 oz infused-edible solid, 216 oz infused-edible liquid, 21 g concentrate.
- Access higher-dose edibles where available (some products are formulated above the 10 mg/piece recreational cap for medical sale).
- Grow a limited number of plants at home if their provider authorizes it (specific plant counts in RCW 69.51A.260).
What this means at the counter
At a medically endorsed store, the card-holding customer presents the recognition card alongside their ID. The system flags the transaction as medical. The sales-tax line drops off the receipt (state and local). The 37% excise stays on. If the customer is buying a high-dose product available only on the medical menu, that line opens up.
At a recreational-only store, the medical card has no effect — the store can only sell from its recreational menu at recreational tax.
Who tends to go medical
The math favors medical for high-volume regular consumers — the sales-tax exemption stacks up across a year of purchases. It also matters for patients who need a higher dose per piece than the 10 mg recreational cap allows. For an occasional consumer buying a $20 edible every few weeks, the paperwork tends to outweigh the tax savings.
What hasn’t changed
The medical program does not authorize use anywhere recreational cannabis is prohibited. No public consumption, no workplace policy exemption, no impaired driving exemption. Medical use is still cannabis use under state law for those purposes.
Finding a medically endorsed store
The DOH publishes a list of medically endorsed retailers. Look for the medical endorsement decal at the door or call ahead before driving over.
