Just recently moved in with some friends of mine, and I smoke, so do my other two roommates. But one of them doesn't and he's getting annoyed by the smell. Well at 3:00 a.m. I don't exactly like getting out of bed and going to the balcony to smoke. I've tried using Smoker's candles but they only mask the smell really. How can I get rid of the smell so that my friend can be happy and I can continue to smoke in my room?
