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 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."
