From Chapter 1:
Who first smoked a pipe of tobacco in England? The honour is divided among several claimants. It has often been stated that Captain William Middleton or Myddelton (son of Richard Middleton, Governor of Denbigh Castle), a Captain Price and a Captain Koet were the first who smoked publicly in London, and that folk flocked from all parts to see them; and it is usually added that pipes were not then invented, so they smoked the twisted leaf, or cigars. This account first appeared in one of the volumes of Pennant's "Tour in Wales." But the late Professor Arber long ago pointed out that the remark as to the mode of smoking by cigars and not by pipes was simply Pennant's speculation. The authority for the rest of the story is a paper in the Sebright MSS., which, in an account of William Middleton, has the remark: "It is sayed, that he, with Captain Thomas Price of Plâsyollin and one Captain Koet, were the first who smoked, or (as they called it) drank tobacco publickly in London; and that the Londoners flocked from all parts to see them." No date is named, and no further particulars are available.

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."
