My roommate and I smoked in our dorm room. We made sure to throw a towel under the door and put a fan in the window every time. I don't know how we didn't get caught. Looking back on it, it was rather stupid.

If the RAs here smell it, they will call the police. Getting caught with alcohol once gets you a warning. Getting caught with marijuana gets you (and your roommates) kicked out of the dorms. Make sure to check your school's rules.

A friend of mine got kicked out of her dorm for smoking during the week before finals. I wouldn't really recommend using your bong anywhere. Blunts, joints, and pocket-bowls are your best friends in college. Large paraphernalia is no good until you have an apartment.
