From Chapter 2:
Among the general audience of the theatre smoking seems to have been usual also. The anti-tobacconists among those present, few of whom were men, must have suffered by the practice. In that admirable burlesque comedy by Beaumont and Fletcher, "The Knight of the Burning Pestle," 1613, the citizen's wife, addressing herself either to the gallants on the stage, or to her fellow-spectators sitting around her, exclaims: "Fy! This stinking tobacco kills men! Would there were none in England! Now I pray, gentlemen, what good does this stinking tobacco do you? Nothing, I warrant you; make chimneys a' your faces!" But many women viewed tobacco differently, as we shall see in the chapter on "smoking by Women." Moreover, this good woman herself, in the epilogue to the burlesque, invites the gentlemen whom she has before abused for smoking, to come to her house where she will entertain them with "a pottle of wine, and a pipe of tobacco."

From Chapter 8:
The allusion in these verses to a "satiric wipe" refers to a passage in the poem entitled "Conversation," which Cowper had written in the previous year, 1781. In this passage tobacco is abused in terms which Cowper clearly felt to need modification after his personal intercourse with such a smoker as his friend Bull. In describing, in "Conversation," the manner in which a story is sometimes told, the poet says:

The pipe, with solemn interposing puff,
Makes half a sentence at a time enough;
The dozing sages drop the drowsy strain,
Then pause and puff—and speak, and pause again.
Such often, like the tube they so admire,
Important triflers! have more smoke than fire.
