i'd say your risk of it affecting your enrollment is extremely slim to none. that being said, i was busted on Western Michigan University's campus in the dorms last year and the cops just left with the tiny amount of pot and never said anything and then 4 months later i got a letter in the mail informing me of a warrant for my arrest

not trying to scare you but college cops are shady fucks. if you say you dealt with some rent-a-cops though you should be pretty safe man

my situation wasnt so lucky tho.....i got caught in january and put on probation in april and im still paying for that shenanigans. my advice would be to just stay away from campuses at night with pot or suck it up and eat it next time
