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 8:
Coleridge, in the "Biographia Literaria," gives an amusing account of his own experience of an attempt to smoke in company with a party of tradesmen. In 1795 he was travelling about the country endeavouring to secure subscriptions to the periodical publication he had started called The Watchman. At Birmingham one day he dined with a worthy tradesman, who, after dinner, importuned him "to smoke a pipe with him, and two or three other illuminati of the same rank." The remainder of the moving story must be told in Coleridge's own words. "I objected," he says, "both because I was engaged to spend the evening with a minister and his friends, and because I had never smoked except once or twice in my life-time, and then it was herb tobacco mixed with Oronooko. On the assurance, however, that the tobacco was equally mild, and seeing too that it was of a yellow colour,—not forgetting the lamentable difficulty I have always experienced in saying, 'No,' and in abstaining from what the people about me were doing,—I took half a pipe, filling the lower half of the bole with salt. I was soon, however, compelled to resign it, in consequence of a giddiness and distressful feeling in my eyes, which, as I had drunk but a single glass of ale, must, I knew, have been the effect of the tobacco. Soon after, deeming myself recovered, I sallied forth to my engagement; but the walk and the fresh air brought on all the symptoms again, and I had scarcely entered the minister's drawing-room, and opened a small pacquet of letters, which he had received from Bristol for me, ere I sank back on the sofa in a sort of swoon rather than sleep. Fortunately I had found just time enough to inform him of the confused state of my feelings, and of the occasion. For here and thus I lay, my face like a wall that is white-washing, deathly pale, and with the cold drops of perspiration running down it from my forehead, while one after another there dropped in the different gentlemen, who had been invited to meet, and spend the evening with me, to the number of from fifteen to twenty. As the poison of tobacco acts but for a short time, I at length awoke from insensibility, and looked round on the party, my eyes dazzled by the candles which had been lighted in the interim. By way of relieving my embarrassment one of the gentlemen began the conversation with 'Have you seen a paper to-day, Mr. Coleridge?' 'Sir,' I replied, rubbing my eyes, 'I am far from convinced that a Christian is permitted to read either newspapers or any other works of merely political and temporary interest.' This remark, so ludicrously inapposite to, or rather, incongruous with, the purpose for which I was known to have visited Birmingham, and to assist me in which they were all met, produced an involuntary and general burst of laughter; and seldom indeed have I passed so many delightful hours as I enjoyed in that room from the moment of that laugh till an early hour the next morning."
