i used to smoke in my room at night after my mom and her bf fell asleep. closed the door, put a towel underneath, then opened window. didnt use a blow tube too much, cause i realized smell didnt stick long.

over the last year, year and a half i got lazy though. i either smoke on my deck(if i roll a joint or blunt), or i just smoke in my living room when their asleep. no blow tube, no axe spraying. then again, i smoke a jack after, which covers the smell.
