From Chapter 3:
A converse view of smoking may be seen in Izaak Walton's "Life" of Sir Henry Wotton, who died in 1639. Walton says that Wotton obtained relief to some extent from asthma by leaving off smoking which he had practised "somewhat immoderately"—"as many thoughtful men do." The italics are mine.

Tobacco, as has been said, was praised as well as abused extravagantly. Much absurdity was written in glorification of the medicinal and therapeutic properties of tobacco, but a more sensible note was struck by some lauders of the weed. Marston wrote in 1607:

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.
