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:
When Tennyson was an undergraduate at Cambridge, 1828-30, he and his companions all smoked. At the meetings of the "Apostles"—the little group of friends which included the future Laureate—"much coffee was drunk, much tobacco smoked." Dons smoked as well as undergraduates. At Queens', the Combination-room in Tennyson's time had still a sanded floor, and the "table was set handsomely forth with long 'churchwardens'"—as the poet told Palgrave when the two visited Cambridge in 1859. George Pryme, in his "Autobiographic Recollections," 1870, states that in 1800 "smoking was allowed in the Trinity Combination-room after supper in the twelve days of Christmas, when a few old men availed themselves of it," which looks as if tobacco were not very popular just then at Trinity. With the wine, pipes and the large silver tobacco-box were laid on the table. Porson, when asked for an inscription for the box, suggested Pryme says that among the undergraduates, of whom he was one, tobacco had no favour, and "an attempt of Mr. Ginkell, son of Lord Athlone ... to introduce smoking at his own wine-parties failed, although he had the prestige of being a hat-fellow-commoner."
