From Chapter 2:
Tobacco was smoked by all classes and in almost all places. It was smoked freely in the streets. In some verses prefixed to an edition of Skelton's "Elinour Rumming" which appeared in 1624, the ghost of Skelton, who was poet-laureate to King Henry VIII, was made to say that he constantly saw smoking:

As I walked between
Westminster Hall
And the Church of Saint Paul,
And so thorow the citie,
Where I saw and did pitty
My country men's cases,
With fiery-smoke faces,
Sucking and drinking
A filthie weede stinking.

Tobacco-selling was sometimes curiously combined with other trades. A Fleet Street tobacconist of this time was also a dealer in worsted stockings. A mercer of Mansfield who died at the beginning of 1624, and who apparently carried on business also at Southwell, had a considerable stock of tobacco. In the Inventory of all his "cattalles and goods" which is dated 24 January 1624, there is included "It. in Tobacco 19.li 0. 0." Nineteen pounds' worth of tobacco, considering the then value of money, was no small stock for a mercer-tobacconist to carry.

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.
