if your room mate smokes then do it, if not then do it and keep it hidden, find someone in your hall who smokes and who you can trust (get to know ppl well... that introduction shit you will run into a lot but if you wanna have friendships that are more than "hey" in the hallways be the bigger man/woman and get to know ppl but dont pry of course ) and put it in his/her room. if it is acceptable with their roomate, that is...

if you have a guitar put it in a guitar case or ull find a good spot for it.
