From Chapter 2:
But the apothecaries were the most usual salesmen, and their shops and the ordinaries were the customary day meeting-places for the more fashionable smokers. The taverns and inns, however, were also filled with smoke, and taverns were frequented by men of all social grades. Dekker speaks of the gallant leaving the tavern at night when "the spirit of wine and tobacco walkes" in his train. On the occasion of the accession of James I, 1603, when London was given up to rejoicing and revelry, we are told that "tobacconists [i.e. smokers] filled up whole Tavernes."

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?
