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 7:
The examples and illustrations which have been given so far in this chapter relate to tradesmen and merchants, country gentlemen and the clergy. Other professional men smoked—we read in Fielding's "Amelia" of a doctor who in the evening "smoked his pillow-pipe, as the phrase is"—and among the rest of the people of equal or lower social standing smoking was as generally practised as in the preceding century. Handel, I may note, enjoyed his pipe. Dr. Burney, when a schoolboy at Chester, was "extremely curious to see so extraordinary a man," so when Handel went through that city in 1741 on his way to Ireland, young Burney "watched him narrowly as long as he remained in Chester," and among other things, had the felicity of seeing the great man "smoke a pipe, over a dish of coffee, at the Exchange Coffee-house," which was under the old Town Hall that stood opposite the present King's School, and in front of the present Town Hall.

Gonzales, in his "Voyage to Great Britain," 1731, says that the use of tobacco was "very universal, and indeed not improper for so moist a climate." He tells us that though the taverns were very numerous yet the ale-houses were much more so. These ale-houses were visited by the inferior tradesmen, mechanics, journeymen, porters, coachmen, carmen, servants, and others whose pockets were not equal to the price of a glass of wine, which, apparently, was the more usual thing to call for at a tavern, properly so called. In the ale-house men of the various classes and occupations enumerated, says the traveller, would "sit promiscuously in common dirty rooms, with large fires, and clouds of tobacco, where one that is not used to them can scarce breathe or see."
