From Chapter 2:
A curious scene took place at Oxford in 1605 when King James visited the University. Two subjects were debated by learned dons before his Majesty, and one of them, at his own suggestion, was, "Whether the frequent use of tobacco is good for healthy men?" Among those who spoke were Doctors Ailworth, Gwyn, Gifford and Cheynell. The discussion, needless to say, being conducted in the presence of the author of the "Counterblaste to Tobacco," was not favourable to the herb. The King summed up in a speech which hopelessly begged the question while it contained plenty of strong denunciation. After his Majesty had spoken, one learned doctor, Cheynell, who is described by the recorder, Isaac Wake, the Public Orator of the University, as second to none of the doctors, had the courage to rise and, with a pipe held forth in his hand, to speak both wittily and eloquently in favour of tobacco from the medicinal point of view, praising it to the skies, says Wake, as of virtue beyond all other remedial agents. His wit pleased both the King and the whole assembly, whom it moved to laughter; but when he had finished, his Majesty made a lengthy rejoinder in which he said some curious things. He objected to the medicinal use of tobacco, and quite agreed with previous speakers that such a use must have arisen among Barbarians and Indians, who he went on to say had as much knowledge of medicine as they had of civilized customs. If, he argued, there were men whose bodies were benefited by tobacco-smoke, this did not so much redound to the credit of tobacco, as it did reflect upon the depraved condition of such men, that their bodies should have sunk to the level of those of Barbarians so as to be affected by remedies such as were effective on the bodies of Barbarians and Indians! His Majesty kindly suggested that doctors who believed in tobacco as a remedial agent should take themselves and their medicine of pollution off to join the Indians.

From Chapter 4:
It is somewhat singular that the Puritans, who denounced most amusements and pleasures, and who frowned upon most of the occupations or diversions that make for gaiety and the enjoyment of life, did not, as Puritans, denounce the use of tobacco. One or two of their writers abused it roundly; but these were not representative of Puritan feeling on the subject. The explanation doubtless is that the practice of smoking was so very general and so much a matter of course among men of all ranks and of all opinions, that the mouths of Puritans were closed, so to speak, by their own pipes. A precisian, however, could take his tobacco with a difference. The seventeenth-century diarist, Abraham de la Pryme, says that he had heard of a Presbyterian minister who was so precise that "he would not as much as take a pipe of tobacco before that he had first sayed grace over it." George Wither, one of the most noteworthy of the poets who took the side of the Parliament, was confined in Newgate after the Restoration, and found comfort in his pipe.

From Chapter 5:
Tobacco was still the symbol of good-fellowship. Winstanley, who was an enemy of what he called "this Heathenish Weed," and who thought the "folly" of smoking might never have spread so much if stringent "means of prevention" had been exercised, yet had to declare in 1660 that "Tobacco it self is by few taken now as medicinal, it is grown a good-fellow, and fallen from a Physician to a Complement. 'He's no good-fellow that's without ... burnt Pipes, Tobacco, and his Tinder-Box.'"

From Chapter 8:
There is ample evidence, apart from Johnson's dictum, that in the latter part of the eighteenth century smoking had "gone out." In Mrs. Climenson's "Passages from the Diaries of Mrs. Lybbe Powys," we hear of a bundle of papers at Hardwick House, near Whitchurch, Oxon, which bears the unvarnished title "Dick's Debts." This Dick was a Captain Richard Powys who had a commission in the Guards, and died at the early age of twenty-six in the year 1768. This list of debts, it appears, gives "the most complete catalogue of the expenses of a dandy of the Court of George II, consisting chiefly of swords, buckles, lace, Valenciennes and point d'Espagne, gold and amber-headed canes, tavern bills and chair hire." But in all the ample detail of Captain Powys's list of extravagances there is nothing directly or indirectly relating to smoking. The beaux of the time did not smoke.
