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:
If smoking had died out at Oxford its decline must have been rapid. When a certain young John James was an undergraduate of Queen's, 1778 to 1781, he and his correspondents spoke severely of the "miserable condition of Fellows who (under the liberal pretence of educating youth) spend half their lives in smoking tobacco and reading the newspapers." About 1800 the older or more old-fashioned of the Fellows at New College, "not liking the then newly introduced luxury of Turkey carpets," says Mr. G.V. Cox, in his "Recollections of Oxford," 1868, "often adjourned to smoke their pipe in a little room opposite to the Senior Common-room, now appropriated to other uses, but then kept as a smoking-room." A Mr. Rhodes, a one-time Fellow of Worcester College, who was elected Esquire Bedel in Medicine and Arts in 1792, had a very peculiar way of enjoying his tobacco. Mr. Cox says: "On one occasion, when I had to call upon him, I found him drinking rum and water, and enjoying (what he called his luxury) the fumes of tobacco, not through a pipe or in the shape of a cigar, but burnt in a dish!"
