From Chapter 2:
The properly accomplished gallant not only professed to be curiously learned in pipes and tobacco, but his knowledge of prices and their fluctuations, of the apothecaries' and other shops where the herb was sold, and of the latest and most fashionable ways of inhaling and exhaling the smoke, was, like Mr. Weller's knowledge of London, "extensive and peculiar." It was knowledge of this kind that gained for a gallant reputation and respect by no means to be acquired by mere scholarship and learning.

From Chapter 5:
If the restored king did not himself smoke, tobacco was far from unknown at the Palace of Whitehall. We get a curious glimpse of one aspect of life there in the picture which Lilly, the notorious astrologer, paints in his story of his arrest in January 1661. He was taken to Whitehall at night, and kept in a large room with some sixty other prisoners till daylight, when he was transferred to the guardroom, which, he says, "I thought to be hell; some therein were sleeping, others swearing, others smoaking tobacco. In the chimney of the room I believe there was two bushels of broken Tobacco Pipes, almost half one load of ashes." What would the king's grandfather, the author of the "Counterblaste," have said, could he have imagined such a spectacle within the palace walls?
