Same as above, if incriminating activity, beyond typical use is occurring in your dorm, do NOT send there. Doesn't sound like it is, so realistically, you have no worries. However, as soon as any resin or residue from use of the grinder is there, it is now paraphernalia. Depending on your state, local, college, etc. this may be illegal. If you want to ship and/or travel with grinder in future, you must wash it. Probably best be is to immerse in rubbing alcohol and let sit.
