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 8:
In the fashionable world the snuff-box was all-powerful. The Prince Regent was devoted to snuff, but disdained tobacco. He had a "cellar of snuff," which after his death was sold, said John Bull, August 15, 1830, "to a well-known purveyor, for £400." Lord Petersham, famous among dandies, made a wonderful collection of snuffs and snuff-boxes, and was curious in his choice of a box to carry. Gronow relates that once when a light Sèvres snuff-box which Lord Petersham was using, was admired, the noble owner replied, with a gentle lisp—"Yes, it is a nice summer box—but would certainly be inappropriate for winter wear!" The well-known purveyor who bought the Prince Regent's cellar of snuff, and who bought also Lord Petersham's stock, was the Fribourg of Fribourg and Treyer, whose well-known old-fashioned shop at the top of the Haymarket, with a bow-window on each side of the door, still gives an eighteenth-century flavour to that thoroughfare. All the dandies of the period were connoisseurs of snuff, and imitated the royal mirror of fashion in their devotion to the scented powder. Young Charles Stanhope wrote to his brother on November 5, 1812—"I have learnt to take snuff among other fashionable acquirements, a custom which, of course, you have learnt and will be able to keep me in countenance." But no dandies or young men of fashion smoked. Tobacco, save in the disguise of snuff, was tabooed.
