The headline number — 37% state excise
Washington charges a 37% excise tax on every cannabis sale at the retail counter. That excise is on top of the sticker price you see on the shelf, and it’s on top of state and local sales tax. It’s the largest single line on your receipt.
The 37% rate has been in place since 2015, when the legislature consolidated three earlier producer/processor/retailer taxes into a single point-of-sale excise. The state collects it, then distributes it across the general fund, the Department of Health’s cannabis education and prevention work, the Liquor and Cannabis Board’s regulatory operations, and a few smaller dedicated buckets.
Plus state + local sales tax
After the 37% excise, the running total gets state sales tax (6.5%) and local sales tax (varies by jurisdiction). Local rates depend on the city and county the store is in, and they’re the same rates that apply to any other retail purchase in that location. The combined effective rate on a cannabis purchase typically lands somewhere between 45% and 48% on top of the listed price.
A worked example
A 1g pre-roll priced at $10 on the shelf:
- Subtotal: $10.00
- 37% excise: +$3.70
- State + local sales tax (call it 10% for a round number): +$1.37
- Total at the counter: about $15.07
The exact local rate at our store is published on the receipt every time, and our budtenders will read it back to you before you pay if you want the breakdown.
Why the price feels high
Cannabis is a federally controlled substance, which means licensed retailers can’t deduct ordinary business expenses (rent, payroll, advertising) the way other small businesses can. That federal tax treatment (IRC §280E) compounds with the state excise to keep retail prices structurally above what you’d see for an equivalent product in an unregulated market. The tax line is the most visible piece; the §280E layer sits under the sticker price itself.
What the tax pays for
The 37% excise funds, in rough order of dollars: the state general fund (which underwrites schools, public safety, and Medicaid match), the Department of Health’s cannabis education and prevention grants, basic health-plan trust account contributions, the Liquor and Cannabis Board’s licensing and enforcement work, and city and county allocations to jurisdictions that allow retail sales.
What it doesn’t cover
The excise doesn’t pay for federal banking access (which is why dispensaries are cash-only) and it doesn’t fund any federal-level cannabis research or rescheduling work. Those are separate federal-policy questions. The state-level tax structure is closed inside Washington.
