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:
The most famous of country clergymen of the early Georgian period is, of course, Fielding's lovable and immortal Parson Adams. Throughout "Joseph Andrews" the parson smokes at every opportunity. At his first appearance on the scene, in the inn kitchen, he calls for a pipe of tobacco before taking his place at the fireside. The next morning, when he fails to obtain a desired loan from the landlord, Adams, extremely dejected at his disappointment, immediately applies to his pipe, "his constant friend and comfort in his affliction," and leans over the rails of the gallery overlooking the inn-yard, devoting himself to meditation, "assisted by the inspiring fumes of tobacco." Later on, in the parlour of the country Justice of the Peace, who condemned his prisoners before he had taken the depositions of the witnesses against them, and who, by the way, also lit his pipe while his clerk performed this necessary duty, Adams, when his character has been cleared, sits down with the company and takes a cheerful glass and applies himself vigorously to smoking. A few hours later, when the parson, Fanny, and their guide are driven by a storm of rain to take shelter in a wayside ale-house, Adams "immediately procured himself a good fire, a toast and ale, and a pipe, and began to smoke with great content, utterly forgetting everything that had happened." In the same inn, after Mrs. Slipslop has appeared and disappeared, Adams smokes three pipes and takes "a comfortable nap in a great chair," so leaving the lovers, Joseph and Fanny, to enjoy a delightful time together.
