From Chapter 2:
It may be noted, by the way, that the gallant had no hesitation about smoking in the presence of ladies. Gostanzo, in Chapman's "All Fools," 1605, says:

And for discourse in my fair mistress's presence
I did not, as you barren gallants do,
Fill my discourses up drinking tobacco.

And in Ben Jonson's "Every Man out of his Humour," 1600, Fastidious Brisk, "a neat, spruce, affecting courtier," smokes while he talks to his mistress. A feather-headed gallant, when in the presence of ladies, often found himself, like others of his tribe of later date, gravelled for lack of matter for conversation, and the puffing of tobacco-smoke helped to occupy the pauses.

When our gallant went to the theatre he loved to occupy one of the stools at the side of the stage. There he could sit and smoke and embarrass the actors with his audible criticisms of play and players.

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.
