The short answer
Yes. In most states, tax still applies to medical cannabis. A patient card rarely makes a purchase tax free by itself. What changes is the rate and which taxes land on the receipt. Medical sales often skip the cannabis-specific excise tax that recreational buyers pay, and a minority of states waive sales tax for registered patients. Local taxes tend to follow the sale no matter who buys.
cannabis sales tax vs excise tax
Which taxes show up on a medical receipt
- State sales tax. The default in most states. Medical may pay the full rate or a reduced one.
- Local sales tax. City and county add-ons, common in states like Colorado and Illinois. A state exemption does not always carry down to the local level.
- Cannabis excise tax. The big one. Rates run from a few percent to more than 20%, and most states apply it only to adult-use sales.
- No federal excise tax. Washington does not tax cannabis sales directly, though IRS rules shape what the seller can write off.
Where medical buyers get relief
Colorado is a clean example. The state's 15% retail marijuana excise tax sits on recreational sales only. Medical patients pay standard state sales tax, currently 2.9%, plus whatever their city charges. That gap is why some cardholders drive past a recreational shop to reach a medical counter.
Where is Cannabis Tax Lowest in the US?
Michigan works the same way on the excise side. The 10% marijuana excise tax applies to adult-use retail. Medical purchases skip it but still carry the 6% state sales tax. The result is a few dollars back on a typical order, not a free pass.

Illinois uses a tiered approach instead. Medical cannabis carries a 1% tax rate, while recreational products can be taxed up to 25% depending on THC content. That spread is the widest in the country, and it shows how much state law, not federal law, decides what a patient pays.
Cannabis Sales Tax vs Excise Tax: The Convenient Pick for Dispensaries
Other states treat medical sales like any other retail transaction. No exemption, no reduced rate. Cardholders pay what everyone else pays at the register.
Why the card alone is not enough
Exemptions usually require proof at the point of sale. A dispensary needs to see a valid state registration, not just a doctor's recommendation, and the discount has to be applied in the system before the transaction closes. If the budtender rings it up as adult-use, the tax stands. Some states also cap how much medical product a patient can buy at the reduced rate in a given period.
The federal layer
Section 280E of the tax code blocks cannabis businesses from deducting ordinary expenses. Dispensaries end up taxed on gross revenue rather than net profit, and that cost gets baked into shelf prices. Federal reclassification talk could change the math down the road, but nothing has changed for patients at the register.
One more federal note. Cannabis is not a deductible medical expense on a federal return. The IRS treats it as a controlled substance rather than a prescribed drug, so it fails the test in section 213. A handful of states allow a medical expense deduction on their own returns. Most do not.
How to know what you will pay
- Check your state revenue department's cannabis tax page, not a dispensary blog.
- Ask whether the medical rate applies to state tax only or to local tax as well.
- Confirm your registration is current and on file with the dispensary before you order.
- Compare the all-in price. Delivery fees and checkout tax matter more than the sticker price now that ordering online is routine.
