i agree with brewshooter.
think it may catch some of the tars too. its not going to filter out the 'out gasing' and smoke that you will either deliberatly or not inhale.
i quit cigarettes too. what worked for me was not buying anymore, finishing what i had around the house, smokable butts. every time i wanted a cig, would lite up the pipe. problem solved. i wont even take an offered cig now. you can and will do it, no luck involved or needed.
