From Chapter 3:
Although tobacco was in such general use it yet had plenty of enemies. It was extravagantly abused and extravagantly praised. Robert Burton, of "Anatomy of Melancholy" fame, like many other writers of his time, was prepared to admit the medicinal value of the herb, though he detested the general habit of smoking. Tobacco was supposed in those days to be "good for" a surprising variety of ailments and diseases; but to explore that little section of popular medicine would be foreign to my purpose. Burton believed in tobacco as medicine; but with regard to habitual smoking he was a worthy follower of King James, the strength of whose language he sought to emulate and exceed when he denounced the common taking of tobacco "by most men, which take it as tinkers do ale"—as "a plague, a mischief, a violent purger of goods, lands, health, hellish, devilish, and damned tobacco, the ruin and overthrow of body and soul." No anti-tobacconist could wish for a more whole-hearted denunciation than that.

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.
