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 8:
A satirical print by Rowlandson contains A Man of Fashion's Journal, dated May 1, 1802. The "man of fashion" rides and drinks, goes to the play, gambles and bets, but his journal contains no reference to smoking. Rowlandson himself smoked, and so did his brother caricaturist, Gillray. Angelo says that they would sometimes meet at such resorts of the "low" as the Bell, the Coal Hole, or the Coach and Horses, and would enter into the common chat of the room, smoke and drink together, and then "sometimes early, sometimes late, shake hands at the door—look up at the stars, say it is a pretty night, and depart, one for the Adelphi, the other to St. James's Street, each to his bachelor's bed."

But outside the fashionable world pipes were still in full blast, and in many places of resort the atmosphere was as beclouded with tobacco-smoke as in earlier days. Grosley, in his "Tour to London," 1765, says that there were regular clubs, which were held in coffee-houses and taverns at fixed days and hours, when wine, beer, tea, pipes and tobacco helped to amuse the company.
