I would assume force users (both Jedi and Sith) would be forbidden by their masters from using anything mind-altering, except maybe in strictly controlled rituals. And for good reason. Can't have people running around, randomly force-pushing strangers from a 120th floor balcony on Coruscant.
Now that you mention it, that's right. While we can't be sure if that drink actually contained alcohol, the size and shape of the glass at least heavily implies it.
I don't know. At least during the high republic era with one master and one student, I'd imagine that getting drunk and accidentally showing everyone around you that you have force powers would be extremely dangerous, even more than for a jedi.
I have long pondered a comedy set in the Star Wars universe. Maybe some beer-swilling, rowdy Jedi. And fortunately Auralnauts fulfilled my dream:
