I think there's a lot of people that drink a glass of wine at dinner maybe? They're not by any means alcoholics but would be included in that 5%, which seems expected I guess.

It's possible that those who drink wine daily, both cluster together and reinforce each other.

Thus, it may seem like a significant proportion of the population from the perspective of someone who does, or hangs around at least 1 such person.
