From Chapter 4:
It is certain that the armies of the Parliament were great smokers, for the finds of seventeenth-century pipes on the sites of their camps have been numerous. A considerable number of pipes of the Caroline period, with the usual small elongated bowls, were found in 1902 at Chichester, in the course of excavating the foundations of the Old Swan Inn, East Street, for building the present branch of the London and County Bank.

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.
