Not trying to be edgy, but it strikes me as odd that, once you remove the obvious historic legacy and economic benefits to government, problem gambling is legal in 2016, but recreational drugs are not.
since recreational drugs make gambling that much more fun, you'd think casinos would be lobbying for legalization.
I don't know, I think doing acid in a casino could be very unpleasant.
It could backfire if the user could plausibly argue they were not in their right mind and that the casino acted maliciously in allowing them to rack up a big debt.
casinos give free alcohol to gamblers
The legal drug that casino's peddle is very much the best drug to extract money from patrons. Weed does not reduce inhibitions in the same way that alcohol does, the only one I can think of that would help the casino's bottom line is cocaine.
you forgot meth. 12 hours of doing the same thing over and over with no regard to loss sounds like a meth addict to me.
