From Chapter 3:
The fumes of dried coltsfoot leaves were used as a remedy in cases of difficulty of breathing, both in ancient Roman times and in Tudor England. Lyte, in his translation, 1578, of Dodoens' "Historie of Plants," says of coltsfoot: "The parfume of the dryed leaves layde upon quicke coles, taken into the mouth through the pipe of a funnell, or tunnell, helpeth suche as are troubled with the shortnesse of winde, and fetche their breath thicke or often, and do [sic] breake without daunger the impostems of the breast." The leaves of coltsfoot and of other plants have often been used as a substitute for tobacco in modern days. A correspondent of Notes and Queries, in 1897, said that when he was a boy he knew an old Calvinist minister, who used to smoke a dried mixture of the leaves of horehound, yarrow and "foal's foot" intermingled with a small quantity of tobacco. He said it was a very good substitute for the genuine article. Similar mixtures, or the leaves of coltsfoot alone, have often been smoked in bygone days by folk who could not afford to smoke tobacco only.

From Chapter 7:
At another inn a country squire is discovered smoking his pipe by the door and the parson promptly joins him. Again, he smokes before he goes to bed, and before he breakfasts the next morning; and when he goes into the inn garden with the host who is willing to trust him, both host and parson light their pipes before beginning to gossip. Farther on, when the hospitable Mr. Wilson takes the weary wayfarers in, Parson Adams loses no time in filling himself with ale, as Fielding puts it, and lighting his pipe. The menfolk—Wilson, Adams and Joseph—have to spend the night seated round the fire, but apparently Adams is the only one who seeks the solace of tobacco. It is significant that Wilson, in telling the story of his dissipated early life, classes smoking with "singing, holloaing, wrangling, drinking, toasting," and other diversions of "jolly companions."
