Well I do this all the time now, and i do it when people are home.. first i spray the vents near me with febreeze just to get that smell goin, then i light up my pipe (dont take huge it's where you may cough or somthing) cover the bowl as im finishing, pull up my doob-tube (bottle filled with dryer sheets) exhale through that, and im home free, i like to give another spray of febreeze when im done just in case.
