Ozium > smoke. One thing I found works even better than just spraying ozium after smoking, is taking some toilet paper, spraying it w/ ozium, and stuffing it in a paper towel tube. Then you exhale your smoke through there, just re-spraying ozium on it every so often. I swear after smoking a couple bowls my room wasn't smoky. Works way better than using dryer sheets for the same purpose. (Tip: poke a hole about 2 cm from the end of the tube and stick like a toothpick through it to hold the TP otherwise if you cough into it you'll just launch the paper out) Be sure to get the blue can, the pink can makes your room smell like a hotel and ass-flowers. You can find it in the car air freshener section of wal-mart for like 5 bucks.
