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:
The week-end habit was strong among London tradesmen in those days. Another Connoisseur paper of 1754 refers to the citizens' country-boxes as dusty retreats, because they were always built in close contiguity to the highway so that the inhabitants could watch the traffic, in the absence of anything more sensible to do, where "the want of London smoke is supplied by the smoke of Virginia tobacco," and where "our chief citizens are accustomed to pass the end and the beginning of every week." In the following year there is a description of a visit to Vauxhall by a worthy citizen with his wife and two daughters. After supper the poor man sadly laments that he cannot have his pipe, because his wife, with social ambitions, deems that it is "ungenteel to smoke, where any ladies are in company."

Again, in the Connoisseur's rival, the World, founded and conducted by Edward Moore, there is a letter, in the number dated February 19, 1756, from a citizen who says: "I have the honour to be a member of a certain club in this city, where it is a standing order, That the paper called the World be constantly brought upon the table, with clean glasses, pipes and tobacco, every Thursday after dinner."
