From Chapter 2:
smoking was soon as common in the country as in London. On Wednesday, April 16, 1621, in the course of a debate in the House of Commons, Sir William Stroud, who seems to have been a worthy disciple of that tobacco-hater, King James I, moved that he "would have tobacco banished wholly out of the kingdom, and that it may not be brought in from any part, nor used amongst us"; and Sir Grey Palmes said "that if tobacco be not banished, it will overthrow 100,000 men in England, for now it is so common that he hath seen ploughmen take it as they are at plough." Perhaps this terrible picture of a ploughman smoking as he followed his lonely furrow did not impress the House so much as Sir Grey evidently thought it would; at all events, tobacco was not banished.

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.
