From Chapter 2:
Ben Jonson has given us an amusing picture of the behaviour of gallants on the Elizabethan stage, in his "Cynthia's Revels." In this scene a child thus mimics the obtrusive beau: "Now, sir, suppose I am one of your genteel auditors, that am come in (having paid my money at the door, with much ado), and here I take my place, and sit downe. I have my three sorts of tobacco in my pocket, my light by me, and thus I begin. 'By this light, I wonder that any man is so mad, to come to see these rascally tits play here—they do act like so many wrens—not the fifth part of a good face amongst them all—and then their musick is abominable—able to stretch a man's ears worse than ten—pillories, and their ditties—most lamentable things, like the pitiful fellows that make them—poets. By this vapour—an't were not for tobacco—I think—the very smell of them would poison me, I should not dare to come in at their gates. A man were better visit fifteen jails—or a dozen or two hospitals—than once adventure to come near them.'" And the young rascal, who at each pause marked by a dash had puffed his pipe, no doubt blowing an extra large "cloud" when he swore "by this vapour," turns to his companions and says: "How is't? Well?" and they pronounce his mimicry "Excellent!"

From Chapter 8:
There is ample evidence, apart from Johnson's dictum, that in the latter part of the eighteenth century smoking had "gone out." In Mrs. Climenson's "Passages from the Diaries of Mrs. Lybbe Powys," we hear of a bundle of papers at Hardwick House, near Whitchurch, Oxon, which bears the unvarnished title "Dick's Debts." This Dick was a Captain Richard Powys who had a commission in the Guards, and died at the early age of twenty-six in the year 1768. This list of debts, it appears, gives "the most complete catalogue of the expenses of a dandy of the Court of George II, consisting chiefly of swords, buckles, lace, Valenciennes and point d'Espagne, gold and amber-headed canes, tavern bills and chair hire." But in all the ample detail of Captain Powys's list of extravagances there is nothing directly or indirectly relating to smoking. The beaux of the time did not smoke.
