From Chapter 2:
Hentzner, the German traveller, who visited London in 1598, speaks of smoking being customary among the audience at plays, who were also supplied with "fruits, such as apples, pears and nuts, according to the season, carried about to be sold, as well as ale and wine." He was struck with the universal prevalence of the tobacco-habit. Not only at plays, but "everywhere else," he says, the "English are constantly smoking tobacco," and then he proceeds to describe how they did it: "They have pipes on purpose made of clay, into the further end of which they put the herb, so dry that it may be rubbed into powder; and putting fire to it, they draw the smoak into their mouths, which they puff out again through their nostrils, like funnels, along with it plenty of phlegm and defluxions from the head." This suggests that the unpleasant and quite unnecessary habit of spitting was common with these early smokers, a suggestion which is amply supported by other contemporary evidence.

From Chapter 6:
There was indeed no diminution of tobacco-smoke in the coffee-houses. A visitor from abroad, Mr. Muralt, a Swiss gentleman, writing about 1696, said that character could be well studied at the coffee-houses. He was probably not a smoker himself, for he goes on to say that in other respects the coffee-houses are "loathsome, full of smoke like a guardroom, and as much crowded." He further observed that it was common to see the clergy of London in coffee-houses and even in taverns, with pipes in their mouths. A native witness of about the same date, Ned Ward, writes sneeringly in his "London Spy," 1699, of the interior of the coffee-house. He saw "some going, some coming, some scribbling, some talking, some drinking, some smoking, others jingling; and the whole room stinking of tobacco, like a Dutch scoot, or a boatswain's cabin.... We each of us stuck in our mouths a pipe of sotweed, and now began to look about us." Ward's contemporary, Tom Brown, took a different tone: he wrote of "Tobacco, Cole and the Protestant Religion, the three great blessings of life!"—as strange a jumble as one could wish for.
