A state proposal could raise the tax on cannabis six percentage points in fiscal year 2027, a few years after the state legalized the substance for Marylanders 21 and older. Gov. Wes Moore announced a budget proposal this month, which includes the possibility of raising the tax from 9 percent to 15 percent. "It's going to slow things down. Slow down the progress the market's been making," Matthew Hersh, general manager of KIP Dispensary in Cockeysville, told WMAR.
