Hi r/legaladvice!

My campus security recently went through my room due to "smell of marijuana" and I didn't have anything actual in it. The only thing I did have was a bowl that had previously been used to smoke that had residue on it. I haven't used the thing in forever, they just found it searching through my wardrobe. I don't know why, I have been in trouble for weed in my room before but I had nothing in my room today besides the bowl.

I doubt very highly the police will be alerted (often this stuff is kept within campus security) but as far as the ramifications of school go if I am called before the dean of something similar, do I have any recourse?
<bot>: Campus security said they smelled weed, looked through my stuff and found a used bowl but absolutely nothing else. I have been in trouble for this before but had absolutely nothing today. Can they prove anything?
