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 7:
Throughout the eighteenth century the use of tobacco for smoking was largely confined to the middle and humbler classes of society. To smoke was characteristic of the "cit," of the country squire, of the clergy (especially of the country parsons), and of those of lower social status. But at the same time it must be borne in mind that then, as since, the dictates of fashion and the conventions of society were little regarded by many artists and men of letters.

In the preceding chapter I quoted from Addison's diary of a retired tradesman in the Spectator of 1712. The periodical publications of a generation or so later paid the great essayist the flattery of imitation in this respect as in others. In the Connoisseur of George Colman and Bonnell Thornton, for instance, there is, in 1754, the description of a citizen's Sunday. The good man, having sent his family to church in the morning, goes off himself to Mother Redcap's, a favourite tavern—suburban in those days—or house of call for City tradesmen. There he smokes half a pipe and drinks a pint of ale. In the evening at another tavern he smokes a pipe and drinks two pints of cider, winding up the inane day at his club, where he smokes three pipes before coming home at twelve to go to bed and sleep soundly.
