From Chapter 4:
One inference at least may be fairly drawn, I think, from this document, and that is that smoking was very popular north as well as south of the Tweed.

Tobacco was certainly cheap in Scotland. The following entries are from a MS. account of household expenses kept by the minister of the parish of Eastwood, near Glasgow, the Rev. William Hamilton. They cover two months only and show that the minister was a furious smoker. The prices given are in Scots currency, the pound Scots being worth about twenty pence sterling:

It may perhaps be interesting to compare with these prices, from which, apparently, it may be inferred that near Glasgow tobacco could be bought for some 5d. a pound, which seems incredibly cheap, the occasional expenditure upon tobacco of a worthy citizen of Exeter some few years earlier. Extracts from the "Financial Diary" of this good man, whose name was John Hayne, and who was an extensive dealer in serges and woollen goods generally, as well as in a smaller degree of cotton goods also, were printed some years ago, with copious annotations, by the late Dr. Brushfield.

From Chapter 7:
In a World of 1755 there is a description of a noisy, hearty, drinking, devil-may-care country gentleman, in which it is said, "he makes no scruple to take his pipe and pot at an alehouse with the very dregs of the people." In a Connoisseur of 1754 a fine gentleman from London, making a visit in a country-house, is taking his breakfast with the ladies in the afternoon, when they had their tea, for, says he, "I should infallibly have perished, had I staied in the hall, amidst the jargon of toasts and the fumes of tobacco." When Horace Walpole was staying with his father at his Norfolk country-seat, Houghton, in September 1737, Gray wrote to him from Cambridge: "You are in a confusion of wine, and roaring, and hunting, and tobacco, and, heaven be praised, you too can pretty well bear it." But Gray had no objection to tobacco. He lived at Cambridge, and the dons and residents there (as at Oxford), not to speak of the undergraduates, were as partial to their pipes as the men who went out from among them to become country parsons, and to share the country squire's liking for tobacco. Gray wrote to Warton from Cambridge in April 1749 saying: "Time will settle my conscience, time will reconcile me to this languid companion (ennui); we shall smoke, we shall tipple, we shall doze together"—a striking picture of University life in the sleepy days of the eighteenth century. Gray's testimony by no means stands alone. In November 1730 Roger North wrote to his son Montague, then an undergraduate at Cambridge, saying: "I would be loath you should confirm the scandal charged upon the universities of learning chiefly to smoke and to drink."
