From Chapter 4:
The variations in price of both Spanish and Virginia tobacco were largely due to the frequent changes in the amount of the duty thereon. In 1604 King James I, newly come to the throne, and full of iconoclastic fervour against the weed, raised the duty to 6s. 8d. per lb. in addition to the original duty of 2d. On March 29, 1615, there was a grant to a licensed importer "of the late imposition of 2s. per lb. on tobacco"—which shows that there must have been considerable fluctuation between 1604 and 1615—while in September 1621 the duty stood at 9d. Through James's reign much dissatisfaction was expressed about the importation of Spanish tobacco, and the outcome of this may probably be seen in the proclamations issued by the King in his last two years forbidding "the importation, buying, or selling tobacco which was not of the proper growth of the colonies of Virginia and the Somers Islands." These proclamations were several times confirmed by Charles I, the latest being on January 8, 1631; but they do not seem to have had much effect.

From Chapter 6:
Thackeray pictures Dryden as sitting in his great chair at Will's Coffee-house, Russell Street, Covent Garden, tobacco-pipe in hand; but there is no evidence that Dryden smoked. The snuff-box was his symbol of authority. Budding wits thought themselves highly distinguished if they could obtain the honour of being allowed to take a pinch from it. Of Dr. Aldrich, who was Dean of Christ Church, Oxford, and who wrote a curious "Catch not more difficult to sing than diverting to hear, to be sung by four men smoaking their pipes," an anecdote has often been related, which illustrates his devotion to the weed. A bet was made by one undergraduate and taken by another, that at whatever time, however early, the Dean might be visited in his own den, he would be found smoking. As soon as the bet had been made the Dean was visited. The pair explained the reason for their call, when Aldrich, who must have been a good-tempered man, said, "Your friend has lost: I am not smoking, only filling my pipe."
