From Chapter 2:
Perhaps the most noteworthy thing about smoking at this period, from the social point of view, was its fashionableness. One of the marked characteristics of the gallant—the beau or dandy or "swell" of the time—was his devotion to tobacco. Earle says that a gallant was one that was born and shaped for his clothes—but clothes were only a part of his equipment. Bishop Hall, satirizing the young man of fashion in 1597, describes the delicacies with which he was accustomed to indulge his appetite, and adds that, having eaten, he "Quaffs a whole tunnel of tobacco smoke"; and old Robert Burton, in satirically enumerating the accomplishments of "a complete, a well-qualified gentleman," names to "take tobacco with a grace," with hawking, riding, hunting, card-playing, dicing and the like. The qualifications for a gallant were described by another writer in 1603 as "to make good faces, to take Tobacco well, to spit well, to laugh like a waiting gentlewoman, to lie well, to blush for nothing, to looke big upon little fellowes, to scoffe with a grace ... and, for a neede, to ride prettie and well."

From Chapter 8:
In the whole sixteen volumes of Walpole's correspondence, as so admirably edited by Mrs. Toynbee, there is scarcely a mention of tobacco; and the same may be said of other collections of letters of the same period—the Selwyn letters, the Delany correspondence, and so on. Neither Walpole nor any member of the world in which he lived would appear to have smoked. In Miss Burney's "Evelina," 1778, from the beginning to the end of the book there is no mention whatever of tobacco or of smoking. Apparently the vulgar Branghtons were not vulgar enough to smoke. Such use of tobacco was considered low, and was confined to the classes of society indicated in the preceding chapter. One of the characters in Macklin's "Love à la Mode," 1760, is described as "dull, dull as an alderman, after six pounds of turtle, four bottles of port, and twelve pipes of tobacco."
