Alcohol is objectively worse than marijuana, but you can't put either cat back in the bag. People are going to get drunk and get high no matter what you legislate, so the answer is ban neither. Or, more realistically, the politicians pick whichever course makes them the most money.

Just to give you an example, Arizona auctioned off the first dispensary permits. So the guys with the plan and the capital and the political clout to jump through local hoops got to open up and rake in literal cash like Pablo Escobar.
