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 8:
smoking was frowned upon, even in places where hitherto it had been allowed. In 1812 the authorities of Sion College ordered "that Coffee and Tea be provided in the Parlour for the Visitors and Incumbents, and in the Court Room for the Curates and Lecturers; and that Pipes and Tobacco be not allowed; and that no Wine be at any time carried into the Court Room, nor any into the Hall after Coffee and Tea shall have been ordered on that day."

The use of tobacco for smoking, as I have said, had reached its nadir—in the fashionable world, that is to say—but the dawn follows the darkest hour, and the revival of smoking was at hand, thanks to the cigar.
