I'm one of those people who don't drink very often but I have a reasonably high tolerance, and I drink whiskys. Its what my mum likes to refer to as "our Scottish genes". I once drank an entire bottle myself while the two girls with me got smashed on a bottle of lambrini between them. They were wobbling all over the place, nearly got hit by a car, and my worst mistake was giggling my head off when I forgot I'd locked my dorm room door and walked straight into it trying to open it.
That said, there's totally a problem with alcoholism around here. Especially the high functioning alcoholics, who aren't really considered alcoholics because they can hold decent jobs. You see it in fiction most commonly with lawyers or judges.
There's also a very uncomfortable stigma around not drinking here. If you go out anywhere at my age (late 20s) and have a nonalcoholic drink, especially in the evening or if someone else is paying, the response is "you can have something stronger" and if you say you don't drink, or don't want to drink, you're expected to explain yourself. I don't get that and it really annoys me that I'm expected to explain my drinking choices to people. And that stupid thing about "don't trust people who don't drink".
(Also, awful story, I once accidentally got my cat drunk when I dropped a glass of Baileys, first drink so I was totally sober don't know how I managed to drop it and before I could do anything she'd shot in and licked it up while I was trying to grab her and get her out of there. It wasn't much and she was fine, don't worry, but if you've ever seen a cat coming round from an operation, it looked a lot like that and if we weren't so worried it would have been hilarious)
