From Chapter 2:
Tobacco engages
Both sexes, all ages,
The poor as well as the wealthy;
From the court to the cottage,
From childhood to dotage,
Both those that are sick and the healthy.

This chapter and the next deal with the history of smoking during the first fifty years after its introduction as a social habit—roughly to 1630.

The use of tobacco spread with extraordinary rapidity among all classes of society. During the latter part of Queen Elizabeth's reign and through the early decades of the seventeenth century tobacco-pipes were in full blast. Tobacco was triumphant.

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."
