From Chapter 1:
In this "Report" Hariot says of the tobacco plant: "There is an herbe which is sowed a part by itselfe and is called by the inhabitants Vppówoc: In the West Indies it hath divers names, according to the severall places and countries where it groweth and is used: The Spaniardes generally call it Tobacco. The leaves thereof being dried and brought into powder: they use to take the fume or smoke thereof by sucking it through pipes made of claie into their stomacke and heade: from whence it purgeth superfluous fleame and other grosse humors, openeth all the pores and passages of the body: by which meanes the use thereof, not only preserveth the body from obstructions: but if also any be, so that they have not beane of too long continuance, in short time breaketh them: wherby their bodies are notably preserved in health, and know not many greevous diseases wherewithall wee in England are oftentimes afflicted."

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."
