A legal cannabis purchase in Rockville is taxed at a combined effective rate of about 12% — all of it from Maryland's state-level taxes, since Rockville does not add a local cannabis tax. Every major Maryland city tracked here carries the same combined rate, because Maryland does not let cities add their own cannabis tax on top of the state rate. On a typical $100.00 dispensary purchase that works out to roughly $12.00 in tax, or about $112.00 out the door.
