i'd wait till they go to bed first...if you're going to smoke in your room that is. But i wouldnt smoke the cigs in ur room...too stinky. Make a doob tube. (toilet paper roll with fabric softener sheets stuffed in it) and blow your smoke through it. If you have a ceiling fan have that running on hi and have a window open. Stick a towel under your door too. Oh and if you have any odor spray thats sposed to eliminate smells use that after u smoke. You shouldnt have a problem if you do all that.
