yeah...honestly dont do it.
this happened at our school last year when I was out that night, one of our good friends decided to use our room to smoke a blunt or two with his buddies.
so me and my roommate come home to see flashlights panning around our darkened room. we thought it was just RA's (so we decided we should break in n get our weed) but when we were running down the hallway a neighbor told us the cops were down there. pretty much one of the scariest times of my life.
Lucky for me my stupid buddy that got is in trouble in the first place hid all of our weed. I guess plain sight is the best place to hide it too, he put it on the table in his room and covered the baggy with a baseball cap.
cops tore apart his place too but never looked under the hat
When it comes down to it you have no privacy in dorms, the school is allowed to search whenever they want pretty much, even if they have courtesy enough to not do it normally. One sniff of bud and you could be done for.
