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 non-smokers were the men of fashion and those who followed them in preferring the snuff-box to the pipe. Sometimes, apparently, they chewed. A World of 1754 pokes fun at the "pretty" young men who "take pains to appear manly. But alas! the methods they pursue, like most mistaken applications, rather aggravate the calamity. Their drinking and raking only makes them look like old maids. Their swearing is almost as shocking as it would be in the other sex. Their chewing tobacco not only offends, but makes us apprehensive at the same time that the poor things will be sick," as they certainly well deserved to be. To chew might be "manly," but it will be observed that smoking is not mentioned. No reputation for manliness could be achieved by even the affectation of a pipe. Similarly, in Bramston's "Man of Taste," various fashionable tastes are described, but there is no mention of tobacco.
