Replying to Best place to hide weed in a dorm in the event of a police search?

I know my rights and have had no problems so far but I'm just trying to be proactive in case the feds roll up with a warrant. There's some snitches on my floor that have already reported me and my roommate for our room smelling like weed. I know the RA and campus PD really can't do shit but if the police come with a warrant they can basically tear the room apart. With that being said, what's the best place to hide a decent-sized mason jar? Drawers, bags, etc. are all out of the question, the only thing I can think of is putting it inside an inner coat pocket or box of cereal. I figured some of you on this site have been thru this before, fire away.
