From Chapter 3:
Sometimes coltsfoot was mixed with tobacco. Ursula, the pig-woman and refreshment-booth keeper in Bartholomew Fair, in Ben Jonson's play of that name, says to her assistant: "Threepence a pipe-full I will have made, of all my whole half-pound of tobacco and a quarter of a pound of coltsfoot mixt with it too to eke it out."

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.
