From Chapter 4:
From the various entries in the "Diary" relating to the purchase of tobacco, it seems clear that there was no shop in Exeter devoted specially or exclusively to the sale of the weed. Hayne bought his supplies from four of the leading goldsmiths of the city, who can be identified by the fact that he had dealings with them in their own special wares, also from two drapers, one grocer, and four other tradesmen (on a single occasion each) whose particular occupations are unknown.

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.
