Because it's legal, and that was the only reason to legalize it...
The state regulates it. Legalization process made it a taxed product, like everything else. Tobacco, Liquor, etc.
Technically it is only state legal it is still federally illegal but yes that is correct that was one of the main reasons why they made it state legal is to have more taxes go to the state
