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 5:
Country gentlemen smoked just as much as town mechanics and tradesmen. In 1688 Hervey, afterwards Earl of Bristol, wrote to Mr. Thomas Cullum, of Hawsted Place, desiring "to be remembered by the witty smoakers of Hawsted." A later Cullum, Sir John, published in 1784 a "History and Antiquities of Hawsted," and in describing Hawsted Place, which was rebuilt about 1570, says that there was a small apartment called the smoking-room—"a name," he says, "it acquired probably soon after it was built; and which it retained with good reason, as long as it stood." I should like to know on what authority Sir John Cullum could have made the assertion that the room was called the smoking-room from so early a date as the end of the sixteenth century. No mention in print of a smoking-room has been found for the purposes of the Oxford Dictionary earlier than 1689. In Shadwell's "Bury Fair" of that date Lady Fantast says to her husband, Mr. Oldwit, who loves to tell of his early meetings with Ben Jonson and other literary heroes of a bygone day, "While all the Beau Monde, as my daughter says, are with us in the drawing-room, you have none but ill-bred, witless drunkards with you in your smoking-room." As Mr. Oldwit himself, in another scene of the same play, says to his friends, "We'll into my smoking-room and sport about a brimmer," there was probably some excuse for his wife's remark. These country smoking-rooms were known in later days as stone-parlours, the floor being flagged for safety's sake; and the "stone-parlour" in many a squire's house was the scene of much conviviality, including, no doubt, abundant smoking.
