From Chapter 1:
King James, in his reference to the "first Author" of what he calls "this abuse," clearly had Sir Walter Raleigh in view, and it is Raleigh with whom in the popular mind the first pipe of tobacco smoked in England is usually associated. The tradition is crystallized in the story of the schoolboy who, being asked "What do you know about Sir Walter Raleigh?" replied: "Sir Walter Raleigh introduced tobacco into England, and when smoking it in this country said to his servant, 'Master Ridley, we are to-day lighting a candle in England which by God's blessing will never be put out'"!

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.
