isnt smoke a suspension? so AFAIK probably all the particulate (tar and porbably THC due to tar being sticky) would sink to teh bottom after time, and youd be left wiht a bottle of carcinogens...yummy. Not to mention it woudl be the ULTIMATE in stale smoke and taste aweful. Not to mention you still gotta blow that smoke out somewhere, its probably even LESS discreet than a pipe.
