Just FYI - I have smoked upstairs while my husband and his friend (who would freak out about me smoking) were downstairs and they had no idea. I hit the bathroom with air freshener (just to mask the smell - the best scents are the spicy-sweet ones like Spiced Cider or Vanilla or anything that smells outdoorsy like Bergamot Coriander or Fresh Pine). My husband had no idea. I often do this and he doesn't notice. (I hope he doesn't read this... he'd be mad if he knew I was smoking in the house!)
