If one to two drinks per week, or a glass of wine with dinner with friends increases your overall happiness because you had healthy relationships, or because you met somebody who opened up some other opportunity for you, that probably is an overall net positive compared to not drinking and thus perhaps not going out.

Inb4 "you shouldn't need to drink to have good friendships" yeah okay but sometimes it can just be fun to loosen up a bit and have a good time with your friends and i don't think looking back on my 20s i'd trade my fun nights out for the alternative (staying in and likely grinding CS. counterstrike, not even computer science). YMMV.
