From Chapter 3:
The number of shops where tobacco was sold in the early days of its triumph seems to have been extraordinary. Barnaby Rich, one of the most prolific parents of pamphlets in an age of prolific writers, wrote a satire on "The Honestie of this Age," which was printed in 1614. In this production Rich declares that every fellow who came into an ale-house and called for his pot, must have his pipe also, for tobacco was then a commodity as much sold in every tavern, inn and ale-house as wine, ale, or beer. He goes on to say that apothecaries' shops, grocers' shops, and chandlers' shops were (almost) never without company who from morning to night were still taking tobacco; and what a number there are besides, he adds, "that doe keepe houses, set open shoppes, that have no other trade to live by but by the selling of tobacco." Rich says he had been told that a list had been recently made of all the houses that traded in tobacco in and near about London, and that if a man might believe what was confidently reported, there were found to be upwards of 7000 houses that lived by that trade; but he could not say whether the apothecaries', grocers' and chandlers' shops, where tobacco was also sold, were included in that number. He proceeds to calculate what the annual expenditure on smoke must be. The number of 7000 seems very large and is perhaps exaggerated. Round numbers are apt to be over rather than under the mark.

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."
