From Chapter 1:
There is little doubt that the smoke of herbs and leaves of various kinds was inhaled in this country, and in Europe generally, long before tobacco was ever heard of on this side the Atlantic. But whatever smoking of this kind took place was medicinal and not social. Many instances have been recorded of the finding of pipes resembling those used for tobacco-smoking in Elizabethan times, in positions and in circumstances which would seem to point to much greater antiquity of use than the form of the pipes supports; but some at least of these finds will not bear the interpretation which has been put upon them, and in other cases the presence of pipes could reasonably be accounted for otherwise than by associating them with the antiquity claimed for them. In any case, the entire absence of any allusions whatever to smoking in any shape or form in our pre-Elizabethan literature, or in mediæval or earlier art, is sufficient proof that from the social point of view smoking did not then exist. The inhaling of the smoke of dried herbs for medicinal purposes, whether through a pipe-shaped funnel or otherwise, had nothing in it akin to the smoking of tobacco for both individual and social pleasure, and therefore lies outside the scope of this book.

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."
