From Chapter 1:
Another Elizabethan who is often said to have smoked the first pipe in England is Ralph Lane, the first Governor of Virginia, who came home with Drake in 1586. Lane is said to have given Sir Walter Raleigh an Indian pipe and to have shown him how to use it. There is no original authority, however, for the statement that Lane first smoked tobacco in England, and, moreover, he was not the first English visitor to Virginia to return to this country. One Captain Philip Amadas accompanied Captain Barlow, who commanded on the occasion of Raleigh's first voyage of discovery, when the country was formally taken possession of and named Virginia in honour of Queen Elizabeth. This was early in 1584. The two captains reached England in September 1584, bringing with them the natives of whom King James I, in his "Counter-blaste to Tobacco," speaks as "some two or three Savage men," who "were brought in, together with this Savage custome," i.e. of smoking. It is extremely improbable that Captains Amadas and Barlow, when reporting to Raleigh on their expedition, did not also make him acquainted with the Indian practice of smoking. This would be two years before the return of Ralph Lane.

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.
