My daughter the soph says that drinking is very big on campus, and that this is a topic of many discussions. She also says its a matter of who you hang with and where you go. In her case, she’s heavily involved with HRSFA*, and their functions are normally dry. Her best friends, she met through HRSFA. So she doesn’t drink a lot.

ETA. To elaborate. A lot of the discussions note the connection between excessive drinking and sexual assault, and how curbing the one could have an impact on the other. So these matters are talked about in official as well as informal contexts. (Rape Culture is one of DD’s political interests, so she probably pays more attention to the topic than other students might.)
