From Chapter 2:
An amusing example of the bragging "tobacconist" is pictured for us in Ben Jonson's "Bobadil." Bobadil may perhaps be somewhat of an exaggerated caricature, but it is probable that the dramatist in drawing him simply exaggerated the characteristic traits of many smokers of the day. This hero, drawing tobacco from his pocket, declares that it is all that is left of seven pounds which he had bought only "yesterday was seven-night." A consumption of seven pounds of tobacco in eight days is a pretty "tall order"! Then he goes on to brag of its quality—your right Trinidado—and to assert that he had been in the Indies, where the herb grows, and where he himself and a dozen other gentlemen had for the space of one-and-twenty weeks known no other nutriment than the fume of tobacco. This again was tolerably "steep" even for this Falstaff-like braggart. He continues with more bombast in praise of the medicinal virtues of the herb—virtues which were then very firmly and widely believed in—and is replied to by Cob, the anti-tobacconist, who, with equal exaggeration on the other side, denounces tobacco, and declares that four people had died in one house from the use of it in the preceding week, and that one had "voided a bushel of soot"!

From Chapter 6:
Thackeray pictures Dryden as sitting in his great chair at Will's Coffee-house, Russell Street, Covent Garden, tobacco-pipe in hand; but there is no evidence that Dryden smoked. The snuff-box was his symbol of authority. Budding wits thought themselves highly distinguished if they could obtain the honour of being allowed to take a pinch from it. Of Dr. Aldrich, who was Dean of Christ Church, Oxford, and who wrote a curious "Catch not more difficult to sing than diverting to hear, to be sung by four men smoaking their pipes," an anecdote has often been related, which illustrates his devotion to the weed. A bet was made by one undergraduate and taken by another, that at whatever time, however early, the Dean might be visited in his own den, he would be found smoking. As soon as the bet had been made the Dean was visited. The pair explained the reason for their call, when Aldrich, who must have been a good-tempered man, said, "Your friend has lost: I am not smoking, only filling my pipe."
