From Chapter 4:
In this country tobacco is said to have invaded even the House of Commons itself. Mr. J.H. Burn, in his "Descriptive Catalogue of London Tokens," writes: "About the middle of the seventeenth century it was ordered: That no member of the House do presume to smoke tobacco in the gallery or at the table of the House sitting as Committees." I do not know what the authority for this order may be, but there is no doubt that smoking was practised in the precincts of the House. In "Mercurius Pragmaticus," December 19-26, 1648, the writer says on December 20, speaking of the excluded members: "Col. Pride standing sentinell at the door, denyed entrance, and caused them to retreat into the Lobby where they used to drink ale and tobacco."

From Chapter 5:
Tobacco was still the symbol of good-fellowship. Winstanley, who was an enemy of what he called "this Heathenish Weed," and who thought the "folly" of smoking might never have spread so much if stringent "means of prevention" had been exercised, yet had to declare in 1660 that "Tobacco it self is by few taken now as medicinal, it is grown a good-fellow, and fallen from a Physician to a Complement. 'He's no good-fellow that's without ... burnt Pipes, Tobacco, and his Tinder-Box.'"
