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 8:
smoking was frowned upon, even in places where hitherto it had been allowed. In 1812 the authorities of Sion College ordered "that Coffee and Tea be provided in the Parlour for the Visitors and Incumbents, and in the Court Room for the Curates and Lecturers; and that Pipes and Tobacco be not allowed; and that no Wine be at any time carried into the Court Room, nor any into the Hall after Coffee and Tea shall have been ordered on that day."

The use of tobacco for smoking, as I have said, had reached its nadir—in the fashionable world, that is to say—but the dawn follows the darkest hour, and the revival of smoking was at hand, thanks to the cigar.
