From Chapter 4:
"A custom lothsome to the eye, hatefull to the Nose, harmefull to the braine, dangerous to the lungs, and in the blacke stinking fume thereof, nearest resembling the horrible Stigian smoke of the pit that is bottomelesse."—James I, A Counterblaste to Tobacco.

From Chapter 4:
The social history of smoking from the point of view of fashion, during the period covered by this and the next two chapters may be summarized in a sentence. Through the middle of the seventeenth century smoking maintained its hold upon all classes of society, but in the later decades there are distinct signs that the habit was becoming less universal; and it seems pretty clear that by the time of Queen Anne, smoking, though still extensively practised in many classes of society, was to a considerable extent out of vogue among those most amenable to the dictates of Fashion.

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.
