From Chapter 9:
Other illustrations of folk who smoked, not cigars, but pipes, may be drawn from "Pickwick," which was published in 1836. At the very beginning, when Mr. Pickwick calls a cab at Saint Martin's-le-Grand, the first cab is "fetched from the public-house, where he had been smoking his first pipe." At Rochester, Mr. Pickwick makes notes on the four towns of Strood, Rochester, Chatham and Brompton, where the military were present in strength, and hence the observant gentleman noted—"The consumption of tobacco in these towns must be very great: and the smell which pervades the streets must be exceedingly delicious to those who are extremely fond of smoking." On the evening of the election at Eatanswill, Tupman and Snodgrass resort to the commercial room of the Peacock Inn, where "the atmosphere was redolent of tobacco-smoke, the fumes of which had communicated a rather dingy hue to the whole room, and more especially to the dusty red curtains which shaded the windows." Here, among others, were the dirty-faced man with a clay pipe, the very red-faced man behind a cigar, and the man with a black eye, who slowly filled a large Dutch pipe with most capacious bowl. Tupman and Snodgrass were of the company and smoked cigars. Sam Weller's father smoked his pipe philosophically. If Sam's "mother-in-law" "flies in a passion, and breaks his pipe, he steps out and gets another. Then she screams wery loud, and falls into 'sterics; and he smokes wery comfortably 'till she comes to agin." What better example could there be of pipe-engendered philosophy? When Mr. Pickwick and Sam look in at old Weller's house of call off Cheapside, they find the boxes full of stage coachmen, drinking and smoking, and among them is the old gentleman himself, "smoking with great vehemence." After having given his son valuable parental advice, "Mr. Weller, senior, refilled his pipe from a tin box he carried in his pocket, and, lighting his fresh pipe from the ashes of the old one, commenced smoking at a great rate."

From Chapter 1:
So far Hariot's "Report" regarded tobacco from the medicinal point of view only; but it is important to note that he goes on to describe his personal experience of the practice of smoking in words that suggest the pleasurable nature of the experience. He says: "We ourselves during the time we were there used to suck it after their maner, as also since our returne, and have found maine [? manie] rare and wonderful experiments of the vertues thereof: of which the relation woulde require a volume by itselfe: the use of it by so manie of late, men and women of great calling as else, and some learned Physitians also, is sufficient witness."
