Students agree that you can basically drink as much as you want around Notre Dame and have little to worry about from campus authorities. At worst, the consequences will be about as severe as a slap on the wrist. On the other end of the spectrum, however, the penalties for both drug use and sex on campus are expulsion. Most students didn't complain about the University's priorities, though they are noticeably different from many other schools.
The bottom line? Drink if you like, but don't use drugs or get caught fooling around. The lenient alcohol policy leaves plenty of room for students to have fun; however, there are hefty fines for overindulgence. Students are expected to be responsible, and there is supervision-if you can't keep things behind closed doors, you will get in trouble for it. Make sure you consider the consequences before you do anything on campus. Don't push things too far and you should be just fine.
