Casinos will love it!
Not sure about that. Alcohol tends to make people overconfident and oblivious to how much money they’re losing. Stoned gamblers will end up sitting at the machines like statues, utterly fascinated by all pretty lights. A lot of them will forget why they’re in Vegas and stay in their rooms with the deadbolt and chain lock at. On the other hand, the restaurants, buffets, and snack vendors will do well.
Casinos are in a quandary: they operate in part as banks, and so they don’t want to risk any violations at the federal level, pot sales and pot possession being some of those violations.
But on the other hand, any self-respecting casino looks at the self-destructive brain-addled potheads stoned out of their minds at their tables and see a 5% increase to their top line.
Can you say, “Yo, pothead, you’ve got two 10s and the dealer shows an ace: split ‘em then double down on both. You can do it, pothead, do it!” And the pothead slowly and meekly complies.
