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:
After King William III was settled on the throne the sum of £600,000 was paid to the Dutch from the English exchequer for money advanced in connexion with his Majesty's expedition, and this amount was paid off by tobacco duties. Granger long ago remarked that most of the eminent divines and bishops of the day contributed very practically to the payment of this revolutionary debt by their large consumption of tobacco. He mentions Isaac Barrow, Dr. Barlow of Lincoln, who was as regular in smoking tobacco as at his meals, and had a high opinion of its virtues, Dr. Aldrich, "and other celebrated persons who flourished about this time, and gave much into that practice." One of the best known of these celebrated persons was Gilbert Burnet, Bishop of Salisbury from 1689, and historian of his own times. He had the reputation of being an inveterate smoker, and was caricatured with a long clay stuck through the brim of the shovel hat, on the breadth of which King William once made remark. The bishop replied that the hat was of a shape suited to his dignity, whereupon the King caustically said, "I hope that the hat won't turn your head."
