From Chapter 2:
Tobacco engages
Both sexes, all ages,
The poor as well as the wealthy;
From the court to the cottage,
From childhood to dotage,
Both those that are sick and the healthy.

This chapter and the next deal with the history of smoking during the first fifty years after its introduction as a social habit—roughly to 1630.

The use of tobacco spread with extraordinary rapidity among all classes of society. During the latter part of Queen Elizabeth's reign and through the early decades of the seventeenth century tobacco-pipes were in full blast. Tobacco was triumphant.

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.
