From Chapter 3:
Although tobacco was in such general use it yet had plenty of enemies. It was extravagantly abused and extravagantly praised. Robert Burton, of "Anatomy of Melancholy" fame, like many other writers of his time, was prepared to admit the medicinal value of the herb, though he detested the general habit of smoking. Tobacco was supposed in those days to be "good for" a surprising variety of ailments and diseases; but to explore that little section of popular medicine would be foreign to my purpose. Burton believed in tobacco as medicine; but with regard to habitual smoking he was a worthy follower of King James, the strength of whose language he sought to emulate and exceed when he denounced the common taking of tobacco "by most men, which take it as tinkers do ale"—as "a plague, a mischief, a violent purger of goods, lands, health, hellish, devilish, and damned tobacco, the ruin and overthrow of body and soul." No anti-tobacconist could wish for a more whole-hearted denunciation than that.

From Chapter 8:
No doubt smoking had its ups and downs at the Universities apart from the set of the main current of fashion. We learn from the invaluable Gunning that at Cambridge about 1786 smoking was going "out of fashion among the junior members of our combination-rooms, except on the river in the evening, when every man put a short pipe in his mouth." "I took great pains," he adds, "to make myself master of this elegant accomplishment, but I never succeeded, though I used to renew the attempt with a perseverance worthy of a better cause." About the same time Dr. Farmer was Master of Emmanuel and the Master was an inveterate smoker. Gunning says that Emmanuel parlour under Farmer's presidency was always open to those who loved pipes and tobacco and cheerful conversation—a very natural collocation of tastes. Farmer's silver tobacco-pipe is still preserved in his old college, while Porson's japanned snuff-box is at Trinity.
