From Chapter 1:
There is little doubt that the smoke of herbs and leaves of various kinds was inhaled in this country, and in Europe generally, long before tobacco was ever heard of on this side the Atlantic. But whatever smoking of this kind took place was medicinal and not social. Many instances have been recorded of the finding of pipes resembling those used for tobacco-smoking in Elizabethan times, in positions and in circumstances which would seem to point to much greater antiquity of use than the form of the pipes supports; but some at least of these finds will not bear the interpretation which has been put upon them, and in other cases the presence of pipes could reasonably be accounted for otherwise than by associating them with the antiquity claimed for them. In any case, the entire absence of any allusions whatever to smoking in any shape or form in our pre-Elizabethan literature, or in mediæval or earlier art, is sufficient proof that from the social point of view smoking did not then exist. The inhaling of the smoke of dried herbs for medicinal purposes, whether through a pipe-shaped funnel or otherwise, had nothing in it akin to the smoking of tobacco for both individual and social pleasure, and therefore lies outside the scope of this book.

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.
