From Chapter 4:
There is a curious entry in Thomas Burton's diary of the proceedings of Cromwell's Parliament, which suggests that there may then have been the luxury of a members' smoking-room. Burton was a member of the Parliaments of Oliver and Richard Cromwell from 1656 to 1659, and made a practice—for which historical students have been and are much his debtors—of taking notes of the debates as he sat in the House. Members sometimes objected to and protested against this note-taking, but Burton quietly went on using his pencil, and though his summaries of speeches are often difficult to follow, argument and sense suffering by compression, he has preserved much very valuable matter. Referring to a debate on January 7, 1656-57, on an attempt to go behind the previously passed Act of Oblivion, the diarist records that "Sir John Reynolds had numbered the House, and said at rising there were 220 at the least, besides tobacconists." This can only mean that there were at least 220 members actually present in the House when it rose, not counting the "tobacconists" or smokers, who were enjoying their pipes, not in the Chamber itself, but in some conveniently adjoining place, which may have been a room for the purpose, or may simply have been the lobby referred to above in the extract from "Mercurius Pragmaticus."

From Chapter 7:
The non-smokers were the men of fashion and those who followed them in preferring the snuff-box to the pipe. Sometimes, apparently, they chewed. A World of 1754 pokes fun at the "pretty" young men who "take pains to appear manly. But alas! the methods they pursue, like most mistaken applications, rather aggravate the calamity. Their drinking and raking only makes them look like old maids. Their swearing is almost as shocking as it would be in the other sex. Their chewing tobacco not only offends, but makes us apprehensive at the same time that the poor things will be sick," as they certainly well deserved to be. To chew might be "manly," but it will be observed that smoking is not mentioned. No reputation for manliness could be achieved by even the affectation of a pipe. Similarly, in Bramston's "Man of Taste," various fashionable tastes are described, but there is no mention of tobacco.
