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 7:
The week-end habit was strong among London tradesmen in those days. Another Connoisseur paper of 1754 refers to the citizens' country-boxes as dusty retreats, because they were always built in close contiguity to the highway so that the inhabitants could watch the traffic, in the absence of anything more sensible to do, where "the want of London smoke is supplied by the smoke of Virginia tobacco," and where "our chief citizens are accustomed to pass the end and the beginning of every week." In the following year there is a description of a visit to Vauxhall by a worthy citizen with his wife and two daughters. After supper the poor man sadly laments that he cannot have his pipe, because his wife, with social ambitions, deems that it is "ungenteel to smoke, where any ladies are in company."

Again, in the Connoisseur's rival, the World, founded and conducted by Edward Moore, there is a letter, in the number dated February 19, 1756, from a citizen who says: "I have the honour to be a member of a certain club in this city, where it is a standing order, That the paper called the World be constantly brought upon the table, with clean glasses, pipes and tobacco, every Thursday after dinner."
