	What the American Medical Association hopes you never learn about its true history
		Blitzing the AMA Journal and thirty-one state and regional medical journals, the start-up tobacco company was eager to publicize its innovative use of diethylene glycol as a hygroscopic agent (to retain moisture), in place of the glycerin used by other manufacturers.
		Philip Morris pegged its campaign on hyping the breakthrough that its cigarettes were consequently "less irritating to the throat." When the corporation approached the Journal with its ads, Dr. Fishbein courteously advised it how to go about conducting acceptable scientific testing to validate its unsubstantiated claims and thereby qualify.
		The cigarette manufacturer was eager to link its product with health benefits, and Dr. Fishbein saw a vast new opportunity for revenues from nonmedical products, despite the fact that by this time in the 1930s medical journals were already publishing studies associating smoking with lung cancer.
