A medical purchase in Massachusetts carries no state excise tax, no standard sales tax and no local cannabis tax. An adult-use purchase carries all of them, so the gap on each receipt is easy to estimate.

The Massachusetts sales tax of 6.25% also applies to all sales of marijuana and marijuana products, but there is no standard sales tax on medical marijuana sales(masscannabiscontrol.com).
A host town may add a local tax of up to 3% of adult-use marijuana retail sales(masscannabiscontrol.com).

Try your own number
Type what you spend in a month, before tax. Pick the local tax if your town charges one. The calculator shows the estimated tax on an adult-use purchase, the tax on a medical purchase and the difference.
The calculator needs JavaScript. Without it, use the table below: it shows the same estimates for five monthly amounts.
