States have their own processes for licensing dispensaries, but in all states where marijuana is legal, businesses that sell marijuana must have a license from the state to do so.

The sales are regulated and taxed by the states at varying rates. Some states implement an excise tax on the sales, which are taxes on a particular good – in this case, marijuana – levied on the seller, which typically passes it on to the consumer by including it in the product’s price.

Provisions outlining the amount of marijuana an adult can legally possess, if adults can grow their own marijuana plants and how the tax revenue is spent vary from state to state.
