Do they put oxygen in drinks you get at a casino or all inclusive resort?

So, I heard that they put oxygen in drinks to make you feel like you’re not drunk at a casino or resort, and I’ve been to several and always wondered why I didn’t feel a buzz like I normally would after some odd drinks. Someone told me today they put oxygen in them, so, curious, does anyone really know if this is true? Makes a little sense but I don’t actually know the science on this and am curious.
