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 practice of selling tobacco in small paper packets was common, and moralists naturally had something to say about the fate of an author's work, when the leaves of his books found their ultimate use as wrappers for the weed. "For as no mortal author," says Addison, "in the ordinary fate and vicissitude of things, knows to what use his works may, some time or other, be applied, a man may often meet with very celebrated names in a paper of tobacco. I have lighted my pipe more than once with the writings of a prelate."
