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.

From Chapter 6:
Addison and Steele smoked, and so did Prior, who seems to have had a weakness at times for low company. After spending an evening with Oxford, Bolingbroke, Pope and Swift, it is recorded that he would go "and smoke a pipe, and drink a bottle of ale, with a common soldier and his wife, in Long Acre, before he went to bed." Some of Prior's poems, as Thackeray caustically remarks, smack not a little of the conversation of his Long Acre friends. Pope for awhile attended the symposium at Button's coffee-house, where Addison was the centre of the coterie—he describes himself as sitting with them till two in the morning over punch and Burgundy amid the fumes of tobacco—but such a way of life did not suit his sickly constitution, and he soon withdrew. It is not likely that he smoked.
