My roommate smokes, is courteous, but I still can't stand it?

Use febreeze and candles and air-fresheners that plug into the wall on high power. It sounds like you are ok with the situation, you just want ways that make it a little bit better. My roomate smokes but she understands that I can't be smelling like a walking cigarette so whenever she smokes she sprays everything with febreeze and washes her hands immediately. we turn up the air-fresheners and open the windows just tiny cracks.
