From Chapter 5:
At the time of the Great Plague all kinds of nostrums were sold and recommended as preservatives or as cures. Most of these perished with the occasion that called them forth; but the names of some have been preserved in a rare quarto tract which was published in the Plague year, 1665, entitled "A Brief Treatise of the Nature, Causes, Signes, Preservation from and Cure of the Pestilence," "collected by W. Kemp, Mr. of Arts." In the list of devices for purifying infected air it is stated that "The American Silver-weed, or Tobacco, is very excellent for this purpose, and an excellent defence against bad air, being smoked in a pipe, either by itself, or with Nutmegs shred, and Rew Seeds mixed with it, especially if it be nosed"—which, I suppose, means if the smoke be exhaled through the nose—"for it cleanseth the air, and choaketh, suppresseth and disperseth any venomous vapour." Mr. Kemp warms to his subject and proceeds with a whole-hearted panegyric that must be quoted in full: "It hath singular and contrary effects, it is good to warm one being cold, and will cool one being hot. All ages, all Sexes, all Constitutions, Young and Old, Men and Women, the Sanguine, the Cholerick, the Melancholy, the phlegmatick, take it without any manifest inconvenience, it quencheth thirst, and yet will make one more able, and fit to drink; it abates hunger, and yet will get one a good stomach; it is agreeable with mirth or sadness, with feasting and with fasting; it will make one rest that wants sleep, and will keep one waking that is drowsie; it hath an offensive smell to some, and is more desirable than any perfume to others; that it is a most excellent preservative, both experience and reason do teach; it corrects the air by Fumigation, and it avoids corrupt humours by Salivation; for when one takes it either by Chewing it in the leaf, or Smoaking it in the pipe, the humors are drawn and brought from all parts of the body, to the stomach, and from thence rising up to the mouth of the Tobacconist, as to the helme of a Sublimatory, are voided and spitten out."

From Chapter 7:
The country gentlemen of the time followed the hounds and enjoyed rural sports of all kinds, drank ale, and smoked tobacco. They had their smoking-rooms too. Walter Gale, schoolmaster at Mayfield, Sussex, noted in his Journal under date March 26, 1751: "I went to Mr. Baker's for the list of scholars, and found him alone in the smoaking-room; he ordered a pint of mild beer for me, an extraordinary thing." Gale himself was a regular smoker, and too fond of pints of ale.

Fielding has immortalized the squire of the mid-eighteenth century in his picture of that sporting, roaring, swearing, drinking, smoking, affectionate, irascible, blundering, altogether extraordinary owner of broad acres, Squire Western. We may shrewdly suspect that the portrait of Western is somewhat over-coloured, and cannot fairly be taken as typical; but there is sufficient evidence to show that in some respects at least—in his enthusiasm for sport and love of ale and tobacco—Western is representative of the country squires of his day.

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 13:
From the evidence so far adduced it may fairly be concluded, I think, that during the seventeenth century smoking was not fashionable, or indeed anything but rare, among the women of the more well-to-do classes, while among women of humbler rank it was an occasional, and in a few districts a fairly general habit.

The same conclusion holds good for the eighteenth century. Among women of the lowest class smoking was probably common enough. In Fielding's "Amelia," a woman of the lowest character is spoken of as "smoking tobacco, drinking punch, talking obscenely and swearing and cursing"—which accomplishments are all carefully noted, because none of them would be applicable to the ordinary respectable female.
