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 6:
The more fashionable folk of the Restoration Era and later began to leave off if not to disdain the smoking-habit. Up to about 1700 smoking had been permitted in the public rooms at Bath, but when Nash then took charge, tobacco was banished. Public or at least fashionable taste had begun to change, and Nash correctly interpreted and led it. Sorbière, who has been quoted in the previous chapter, remarked in 1663 that "People of Quality" did not use tobacco so much as others; and towards the end of the century and in Queen Anne's time the tendency was for tobacco to go out of fashion. This did not much affect its general use; but the tendency—with exceptions, no doubt—was to restrict the use of tobacco to the clergy, to country squires, to merchants and tradesmen and to the humbler ranks of society—to limit it, in short, to the middle and lower classes of the social commonwealth as then organized. In the extraordinary record of inanity which Addison printed as the diary of a citizen in the Spectator of March 4, 1712, the devotion of the worthy retired tradesman to tobacco is emphasized. This is the kind of thing: "Monday ... Hours 10, 11 and 12 Smoaked three Pipes of Virginia ... one o'clock in the afternoon, chid Ralph for mislaying my Tobacco-Box.... Wednesday ... From One to Two Smoaked a Pipe and a half.... Friday ... From Four to Six. Went to the Coffee-house. Met Mr. Nisby there. Smoaked several Pipes."
