You people are way to smart. I quote "the tobacco enigma was used to infuse tobacco into a patients rectum for various medical reasons, primarily the resuscitation of drowning victims.
A rectal tube inserted into the anus was connected to a fumigator and bellows that forced the smoke towards the rectum.
The warmth of the smoke was thought to promote respiration but doubts about the credibility of tobacco enemas led to the popular phrase.....blowing smoke up your arse."
Most of our present day gov't reps have one of these.
