smoke in your bathroom close doors with a towel underneath the door,open the window if you have one and remove any other towel clothing ect, for the meantime while you smoke. Then when you're done or while you're smoking to save time turn on the shower on HOT and throw some shampoo or bodywash w/e you have in the tub the steam and shampoo will cover up the smell, kinda of boring but sometimes you have to do what you have to.
