From Chapter 2:
When Robert, Earl of Essex, and Henry, Earl of Southampton, were tried for high treason in Westminster Hall on February 19, 1600-1, the members of the House of Lords, who with the Judges formed the Court, if we may believe the French Ambassador of the time, behaved in a remarkable and unseemly manner. In a letter to Monsieur de Rohan, the Ambassador declared that while the Earls and the Counsel were pleading, their lordships guzzled and smoked; and that when they gave their votes condemning the two Earls, they were stupid with eating and "yvres de tabac"—drunk with smoking. This was probably quite untrue as a representation of what actually took place; but it would hardly have been written had smoking not been a common practice among noble lords.

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."
