From Chapter 4:
Among the documents in the possession of the Society of Antiquaries of Scotland there is a letter patent under the great seal of Charles I, in 1634, granted for the purpose of correcting the irregular sales and restraining the immoderate use of tobacco in Scotland. The letter states that tobacco was used on its first introduction as a medicine, but had since been so largely indulged in and was frequently of such bad quality, as not only to injure the health, but deprave the morals of the King's subjects. These were sentiments worthy of King James. Mr. Matthew Livingstone, who has calendared this document, says that the King therein proceeds, in order to prevent such injurious results of the use of tobacco, to appoint Sir James Leslie and Thomas Dalmahoy to enjoy for seven years the sole power of appointing licensed vendors of the commodity. These vendors, after due examination as to their fitness, were to be permitted, on payment of certain compositions and an annual rent in augmentation of the King's revenue, to sell tobacco in small quantities. The letter further directs that the licensees so appointed shall become bound to sell only sound tobacco—an admirable provision, if a trifle difficult to enforce—and to keep good order in their houses and shops. "The latter clause," adds Mr. Livingstone, "would almost suggest that the tobacco was to be sold for consumption on the premises,"—as I have no doubt it was—"and that the smokers were probably in the habit at their symposiums of using, even as they may still, I dare say, other indulgences not so soothing in their effects as the coveted weed"—a suggestion for which there seems little foundation in the clause to which Mr. Livingstone refers.

From Chapter 6:
The more fashionable folk of the Restoration Era and later began to leave off if not to disdain the smoking-habit. Up to about 1700 smoking had been permitted in the public rooms at Bath, but when Nash then took charge, tobacco was banished. Public or at least fashionable taste had begun to change, and Nash correctly interpreted and led it. Sorbière, who has been quoted in the previous chapter, remarked in 1663 that "People of Quality" did not use tobacco so much as others; and towards the end of the century and in Queen Anne's time the tendency was for tobacco to go out of fashion. This did not much affect its general use; but the tendency—with exceptions, no doubt—was to restrict the use of tobacco to the clergy, to country squires, to merchants and tradesmen and to the humbler ranks of society—to limit it, in short, to the middle and lower classes of the social commonwealth as then organized. In the extraordinary record of inanity which Addison printed as the diary of a citizen in the Spectator of March 4, 1712, the devotion of the worthy retired tradesman to tobacco is emphasized. This is the kind of thing: "Monday ... Hours 10, 11 and 12 Smoaked three Pipes of Virginia ... one o'clock in the afternoon, chid Ralph for mislaying my Tobacco-Box.... Wednesday ... From One to Two Smoaked a Pipe and a half.... Friday ... From Four to Six. Went to the Coffee-house. Met Mr. Nisby there. Smoaked several Pipes."
