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:
With the reign of Queen Anne tobacco had entered on a period, destined to be of long duration, when smoking was to a very large extent under a social ban. Pipe-smoking was unfashionable—that is to say, was not practised by men of fashion, and was for the most part regarded as "low" or provincial—from the time named until well into the reign of Queen Victoria. The social taboo was by no means universal—some of the exceptions will be noted in these pages—but speaking broadly, the general, almost universal smoking of tobacco which had been characteristic of the earlier decades of the seventeenth century did not again prevail until within living memory.
