Great financial report from Marijuana Policy Project on the total amount of tax revenue EVER collected from legal marijuana sales in America since 2014, or basically since Colorado started the whole ball of wax in 2014. The $10.4 billion in state tax revenue is stunning when consider only a handful of states were collecting tax revenue from 2014 to almost 2019. Add in the slow rollouts in many states like Massachusetts, and the lack of sales in highly populated states like Florida and New York, and you realize that number could be double if things had moved faster on the policy side.
