From Chapter 2:
In the afternoon the gallant might attend what Dekker calls a "Tobacco-ordinary," by which may possibly have been meant a smoking-club, or, more probably, the gathering after dinner at one of the many ordinaries in the neighbourhood of St. Paul's Cathedral of "tobacconists," as smokers were then called, to discuss the merits of their respective pipes, and of the various kinds of tobacco—"whether your Cane or your Pudding be sweetest."

Of course he often bragged, like Julio in Day's "Law Trickes": "Tobacco? the best in Europe, 't cost me ten Crownes an ounce, by this vapour."

From Chapter 6:
After King William III was settled on the throne the sum of £600,000 was paid to the Dutch from the English exchequer for money advanced in connexion with his Majesty's expedition, and this amount was paid off by tobacco duties. Granger long ago remarked that most of the eminent divines and bishops of the day contributed very practically to the payment of this revolutionary debt by their large consumption of tobacco. He mentions Isaac Barrow, Dr. Barlow of Lincoln, who was as regular in smoking tobacco as at his meals, and had a high opinion of its virtues, Dr. Aldrich, "and other celebrated persons who flourished about this time, and gave much into that practice." One of the best known of these celebrated persons was Gilbert Burnet, Bishop of Salisbury from 1689, and historian of his own times. He had the reputation of being an inveterate smoker, and was caricatured with a long clay stuck through the brim of the shovel hat, on the breadth of which King William once made remark. The bishop replied that the hat was of a shape suited to his dignity, whereupon the King caustically said, "I hope that the hat won't turn your head."
