From Chapter 2:
But the apothecaries were the most usual salesmen, and their shops and the ordinaries were the customary day meeting-places for the more fashionable smokers. The taverns and inns, however, were also filled with smoke, and taverns were frequented by men of all social grades. Dekker speaks of the gallant leaving the tavern at night when "the spirit of wine and tobacco walkes" in his train. On the occasion of the accession of James I, 1603, when London was given up to rejoicing and revelry, we are told that "tobacconists [i.e. smokers] filled up whole Tavernes."

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."
