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:
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.
