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 5:
Country gentlemen smoked just as much as town mechanics and tradesmen. In 1688 Hervey, afterwards Earl of Bristol, wrote to Mr. Thomas Cullum, of Hawsted Place, desiring "to be remembered by the witty smoakers of Hawsted." A later Cullum, Sir John, published in 1784 a "History and Antiquities of Hawsted," and in describing Hawsted Place, which was rebuilt about 1570, says that there was a small apartment called the smoking-room—"a name," he says, "it acquired probably soon after it was built; and which it retained with good reason, as long as it stood." I should like to know on what authority Sir John Cullum could have made the assertion that the room was called the smoking-room from so early a date as the end of the sixteenth century. No mention in print of a smoking-room has been found for the purposes of the Oxford Dictionary earlier than 1689. In Shadwell's "Bury Fair" of that date Lady Fantast says to her husband, Mr. Oldwit, who loves to tell of his early meetings with Ben Jonson and other literary heroes of a bygone day, "While all the Beau Monde, as my daughter says, are with us in the drawing-room, you have none but ill-bred, witless drunkards with you in your smoking-room." As Mr. Oldwit himself, in another scene of the same play, says to his friends, "We'll into my smoking-room and sport about a brimmer," there was probably some excuse for his wife's remark. These country smoking-rooms were known in later days as stone-parlours, the floor being flagged for safety's sake; and the "stone-parlour" in many a squire's house was the scene of much conviviality, including, no doubt, abundant smoking.
