It's really hard for roommates to smoke in the dormitory, and it's really hard for non-smokers to smell the smoke. For this behavior of your roommate, first of all, you can euphemistically say that his smoking affects you and ask him not to smoke in the dormitory as much as possible. In addition, a dormitory code of conduct can be formulated, which clearly indicates that smoking is not allowed in the dormitory. If the first two methods fail, it is suggested to report directly to the counselor and ask the counselor to remind the roommate not to smoke.

Formulate a dormitory code of conduct and clearly stipulate that smoking is not allowed in the dormitory.
