From Chapter 3:
A converse view of smoking may be seen in Izaak Walton's "Life" of Sir Henry Wotton, who died in 1639. Walton says that Wotton obtained relief to some extent from asthma by leaving off smoking which he had practised "somewhat immoderately"—"as many thoughtful men do." The italics are mine.

Tobacco, as has been said, was praised as well as abused extravagantly. Much absurdity was written in glorification of the medicinal and therapeutic properties of tobacco, but a more sensible note was struck by some lauders of the weed. Marston wrote in 1607:

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.
