Voters will get the chance to decide in April if Anchorage should tax marijuana sales within the municipality, following a 9-2 vote by the Anchorage Assemble Tuesday night.

If approved by voters, the measure would initially tax all marijuana sales at 5 percent. It also gives the Assembly the option to raise that tax by up to 2 percent every two years, with a 12 percent cap.

Supporters say the municipality needs the tax so they can enforce regulations, but some who are planning to open pot businesses say if it goes too high, their customers will buy it for cheaper on the black market.

Assemblyman Patrick Flynn made a surprising announcement during the meeting. He told the assembly he may jump into a marijuana businesses, and wanted to know if he could join the discussion.

Assembly Chair Dick Traini said yes. But if Flynn asks for a permit, that’s a whole different issue.
