From Chapter 4:
Among the documents in the possession of the Society of Antiquaries of Scotland there is a letter patent under the great seal of Charles I, in 1634, granted for the purpose of correcting the irregular sales and restraining the immoderate use of tobacco in Scotland. The letter states that tobacco was used on its first introduction as a medicine, but had since been so largely indulged in and was frequently of such bad quality, as not only to injure the health, but deprave the morals of the King's subjects. These were sentiments worthy of King James. Mr. Matthew Livingstone, who has calendared this document, says that the King therein proceeds, in order to prevent such injurious results of the use of tobacco, to appoint Sir James Leslie and Thomas Dalmahoy to enjoy for seven years the sole power of appointing licensed vendors of the commodity. These vendors, after due examination as to their fitness, were to be permitted, on payment of certain compositions and an annual rent in augmentation of the King's revenue, to sell tobacco in small quantities. The letter further directs that the licensees so appointed shall become bound to sell only sound tobacco—an admirable provision, if a trifle difficult to enforce—and to keep good order in their houses and shops. "The latter clause," adds Mr. Livingstone, "would almost suggest that the tobacco was to be sold for consumption on the premises,"—as I have no doubt it was—"and that the smokers were probably in the habit at their symposiums of using, even as they may still, I dare say, other indulgences not so soothing in their effects as the coveted weed"—a suggestion for which there seems little foundation in the clause to which Mr. Livingstone refers.

From Chapter 7:
Throughout the eighteenth century the use of tobacco for smoking was largely confined to the middle and humbler classes of society. To smoke was characteristic of the "cit," of the country squire, of the clergy (especially of the country parsons), and of those of lower social status. But at the same time it must be borne in mind that then, as since, the dictates of fashion and the conventions of society were little regarded by many artists and men of letters.

In the preceding chapter I quoted from Addison's diary of a retired tradesman in the Spectator of 1712. The periodical publications of a generation or so later paid the great essayist the flattery of imitation in this respect as in others. In the Connoisseur of George Colman and Bonnell Thornton, for instance, there is, in 1754, the description of a citizen's Sunday. The good man, having sent his family to church in the morning, goes off himself to Mother Redcap's, a favourite tavern—suburban in those days—or house of call for City tradesmen. There he smokes half a pipe and drinks a pint of ale. In the evening at another tavern he smokes a pipe and drinks two pints of cider, winding up the inane day at his club, where he smokes three pipes before coming home at twelve to go to bed and sleep soundly.
