From Chapter 5:
General Monk, to whom Charles II owed so much, is said to have indulged in the unpleasant habit of chewing tobacco, and to have been imitated by others; but the practice can never have been common.

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."

From Chapter 3:
One of the most curious of the early publications on tobacco, in which an attempt is made to hold the balance fairly between the legitimate use and the "licentious" abuse of the herb, is Tobias Venner's tract with the long-winded title: "A Brief and Accurate Treatise concerning The taking of the Fume of tobacco, Which very many, in these dayes doe too licenciously use. In which the immoderate, irregular, and unseasonable use thereof is reprehended, and the true nature and best manner of using it, perspicuously demonstrated." Venner described himself as a doctor of physic in Bath, and his tract was published in London in 1637. Venner says that tobacco is of "ineffable force" for the rapid healing of wounds, cuts, sores and so on, by external application, but thinks little of its use for any other purpose. Like others of his school, he attacks the "licentious Tobacconists [smokers] who spend and consume, not only their time, but also their health, wealth, and witts in taking of this loathsome and unsavorie fume." He admits the popularity of the herb, but expresses his own personal objection to the "detestable savour or smack that it leaveth behind upon the taking of it"; from which one is inclined to surmise that the doctor's first pipe was not an entire success. With an evident desire to be fair, Venner, notwithstanding his dislike of the "savour," refuses to condemn tobacco utterly, because of what he considers its valuable medicinal qualities, and he goes so far as to give "10 precepts in the use of" tobacco. The sixth is "that you drink not between the taking of the fumes, as our idle and smoakie Tobacconists are wont"—there must be no alliance, in short, between the pipe and the cheerful glass. The tenth and last precept is "that you goe not abroad into the aire presently [immediately] upon the taking of the fume, but rather refrain therefrom the space of halfe an houre, or more, especially if the season be cold, or moist." The suggestion that the smoker, when he has finished his pipe, shall wait for half an hour or so before he ventures into the outer air is very quaint.

From Chapter 3:
Trickery of another kind is revealed in a scene in Chapman's play "A Humorous Day's Mirth," 1599. A customer at an ordinary says: "Hark you, my host, have you a pipe of good tobacco?" "The best in the town," says mine host, after the manner of his class. "Boy, dry a leaf." Quietly the boy tells him, "There's none in the house, sir," to which the worthy host replies sotto voce, "Dry a dock leaf." But the diner's potations must have been powerful if they had left him unable to distinguish between the taste of tobacco and that of dried dock-leaf.
