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 7:
Fielding himself smoked his pipe. When his play "The Wedding Day" was produced by Garrick in 1743, various suggestions were made to the author as to the excision of certain passages, and the modification of one of the scenes. Garrick pressed for certain omissions, but—"No, damn them," said Fielding, "if the scene is not a good one, let them find that out"; and then, according to Murphy, he retired to the green-room, where, during the progress of the play, he smoked his pipe and drank champagne. Presently he heard the sound of hissing, and when Garrick came in and explained that the audience had hissed the scene he had wished to have modified, all Fielding said was: "Oh, damn them, they have found it out, have they!"

Simon Fraser, Lord Lovat, the crafty old Jacobite who took part in the rising of 1745 and who was executed on Tower Hill in 1747, was a smoker. The pipe which he was reported to have smoked on the evening before his execution, together with his snuff-box and a canvas tobacco-bag, were for many years in the possession of the Society of Cogers, the famous debating society of Fleet Street.
