5 just go into the bathroom and pretend to to take a shower. BEfore you start smoking wait for steam to start coming from the shower, then put a towel at the crack f the door and just blow out the window. I do it all the time and never get caught. The steam totally kills the smell. Maybe spray some freshner after if ur not sure but wut ur doing seems like too much to me. For bonus points use a doob tube when u blow out the window but i dont that cuz what im doing works prettyfine. Also start burning sage, if she ever smells something just blame it on the sage cuz they have simialar smells. It has beenvery effective for me.
