In practice that trims roughly $17.00 off every $100.00 spent versus an adult-use purchase in Cambridge, though the 3% Cambridge cannabis business tax may still apply depending on the local ordinance.
Why Is Cannabis Taxed This Much in Cambridge?
Cannabis in Cambridge carries layers of tax that ordinary retail goods never see. Massachusetts adds its 10.75% cannabis excise on top of ordinary sales tax, and Cambridge then collects an additional 3% cannabis business tax on licensed retailers — a cost dispensaries pass through to the customer. That stacking is why the register total at a Cambridge dispensary can run noticeably higher than the same product in a lower-tax Massachusetts city or across the state line.
10.75% state cannabis excise + 6.25% state sales tax + up to 3% local option tax. Medical marijuana is exempt from all three.
