From Chapter 2:
It chaunc'd me gazing at the Theater,
To spie a Lock-Tabacco Chevalier
Clowding the loathing ayr with foggie fume
Of Dock Tobacco friendly foe to rhume—

says a versifier of 1599, who did not like smoking in the theatre and so abused the quality of the tobacco smoked—though admitting its medicinal virtue. Dekker suggests, probably with truth, that one reason why the young gallant liked to push his way to a stool on the stage, notwithstanding "the mewes and hisses of the opposed rascality"—the "mewes" must have been the squeals or whistles produced by the instrument which was later known as a cat-call—was the opportunity such a prominent position afforded for the display of "the best and most essential parts of a gallant—good cloathes, a proportionable legge, white hand, the Persian lock, and a tolerable beard." Apparently, too, serving-boys were within call, and thus lights could easily be obtained, which were handed to one another by the smokers on the points of their swords.

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.
