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 6:
But so early as 1655 there is a sign of change of custom—a change, that is, in the direction of restricting and limiting the hitherto unbounded freedom granted to the use of tobacco. The London Society of Apothecaries on August 15, 1655, held a meeting for the election of a Master and an Upper Warden; and from the minutes of this meeting we learn that by general consent it was forbidden henceforward to smoke in the Court Room while dining or sitting, under penalty of half a crown.
