From Chapter 1:
Another tradition gives the old Pied Bull at Islington, long since demolished, as the scene of the momentous event. It is said in its earlier days to have been a country house of Sir Walter's, and according to legend it was in his dining-room in this house that he had his first pipe. Hone, in the first volume of the "Every Day Book" tells how he and some friends visited this Pied Bull, then in a very decayed condition, and smoked their pipes in the dining-room in memory of Sir Walter. From the recently published biography of William Hone by Mr. F.W. Hackwood, we learn that the jovial party consisted of William Hone, George Cruikshank, Joseph Goodyear, and David Sage, who jointly signed a humorous memorandum of their proceedings on the occasion, from which it appears that "each of us smoked a pipe, that is to say, each of us one or more pipes, or less than one pipe, and the undersigned George Cruikshank having smoked pipes innumerable or more or less," and that "several pots of porter, in aid of the said smoking," were consumed, followed by bowls of negus made from "port wine @ 3s. 6d. per bottle (duty knocked off lately)" and other ingredients. Speeches were made and toasts proposed, and altogether the four, who desired to "have the gratification of saying hereafter that we had smoked a pipe in the same room that the man who first introduced tobacco smoked in himself," seem to have thoroughly enjoyed themselves.

From Chapter 8:
Says the Pipe to the Snuff-box, I can't understand
What the ladies and gentlemen see in your face,
That you are in fashion all over the land,
And I am so much fallen into disgrace.
- William Cowper.
(From a letter to the Rev. John Newton, May 28, 1782.)

"smoking has gone out," said Johnson in talk at St. Andrews, one day in 1773. "To be sure," he continued, "it is a shocking thing, blowing smoke out of our mouths into other people's mouths, eyes and noses, and having the same thing done to us; yet I cannot account why a thing which requires so little exertion, and yet preserves the mind from total vacuity, should have gone out." Johnson did not trouble himself to think of how much the vagaries of fashion account for stranger vicissitudes in manners and customs than the rise and fall of the smoking-habit; nor did he probably foresee how slowly but surely the taste for smoking, even in the circles most influenced by fashion, would revive. Boswell tells us that although the sage himself never smoked, yet he had a high opinion of the practice as a sedative influence; and Hawkins heard him say on one occasion that insanity had grown more frequent since smoking had gone out of fashion, which shows that even Johnson could fall a victim to the post hoc propter hoc fallacy.
