19 No Legal Cannabis Market
Cannabis is taxed more heavily than almost any other legal product in the United States. Three tax layers stack on every retail purchase: a state excise tax (often 10–37% of retail), the normal state and local sales tax, and in many cities a separate cannabis business tax collected by the municipality. Washington leads the country with a 37% excise on top of sales tax. California, Nevada, Illinois, and Massachusetts all land between 20–30% once city taxes are included.
Medical cannabis is taxed differently in most states. Registered medical patients are often exempt from the recreational excise tax and sometimes from state sales tax — the difference can be 15 percentage points or more on the same product. Use the calculator to see exactly what a purchase would cost in any state, with or without a medical card.
Which US state has the highest cannabis tax?
Washington has the highest combined cannabis tax in the country at roughly 46% once its 37% excise, state sales tax, and typical local sales tax are stacked. California, Illinois, Massachusetts, Colorado, and Nevada regularly land in the 25–35% range once city cannabis business taxes are included.
Which state has the lowest cannabis tax?
Among states with a legal adult-use market, Delaware and New Jersey tend to have the lowest combined effective rate (roughly 7–10%). Washington, DC has no legal adult-use retail market but operates a gifting and medical model with minimal sales tax on medical cannabis.
Why is cannabis taxed so much more than alcohol or tobacco?
States treat cannabis excise taxes as a "sin tax" to cover the cost of regulation, public-health programs, and in some states school or infrastructure funding. Because cannabis is still federally illegal, producers and retailers also can't deduct ordinary business expenses under IRS code §280E, which pushes retail prices (and the effective tax burden on consumers) higher.
Are medical cannabis patients taxed the same as recreational buyers?
Not in most states. Registered medical patients are usually exempt from the recreational excise tax and often from state sales tax — the difference can be 15–25 percentage points on the same product. A handful of states (such as Washington) tax medical and adult-use purchases identically. Use the
tax calculator to compare, or check each
state page for the medical exemption details.
Can cities charge their own cannabis tax on top of state tax?
Yes. California, Michigan, Massachusetts, and several other states let cities add a local cannabis business tax (usually 3–15%) on top of state excise and sales tax. Los Angeles, Oakland, and Denver all sit at or near the top end. Browse our
state pages to see city-level rates for ~105 major US cities.
How much tax will I actually pay on a $100 cannabis purchase?
It depends on the state and city. $100 at a Los Angeles, CA dispensary becomes roughly $134.50 at the register after excise + state sales + city cannabis business tax. The same $100 in Trenton, NJ is closer to $108.63. Use the
calculator to model any state or city in seconds.
Do Canadian and US cannabis taxes work the same way?
No. Canada uses a single federal excise duty (~10% baked into producer price) plus provincial HST or GST+PST at retail — combined effective rates run about 15–25%. US states each impose their own excise tax on top of state + local sales tax, and cities can layer additional cannabis business taxes. See our
Canada tax hub for a full province-by-province breakdown.
How often do cannabis tax rates change?
Excise rates change by legislation (usually once or twice a year), but city cannabis business taxes can change by local ordinance at any time. Our rates were compiled for 2026 (dataset last updated 2026-08-11), a weekly job checks each state's official revenue-department source page for changes, and every state page links its official source so you can confirm the current rate before relying on it.
