From Chapter 3:
The number of shops where tobacco was sold in the early days of its triumph seems to have been extraordinary. Barnaby Rich, one of the most prolific parents of pamphlets in an age of prolific writers, wrote a satire on "The Honestie of this Age," which was printed in 1614. In this production Rich declares that every fellow who came into an ale-house and called for his pot, must have his pipe also, for tobacco was then a commodity as much sold in every tavern, inn and ale-house as wine, ale, or beer. He goes on to say that apothecaries' shops, grocers' shops, and chandlers' shops were (almost) never without company who from morning to night were still taking tobacco; and what a number there are besides, he adds, "that doe keepe houses, set open shoppes, that have no other trade to live by but by the selling of tobacco." Rich says he had been told that a list had been recently made of all the houses that traded in tobacco in and near about London, and that if a man might believe what was confidently reported, there were found to be upwards of 7000 houses that lived by that trade; but he could not say whether the apothecaries', grocers' and chandlers' shops, where tobacco was also sold, were included in that number. He proceeds to calculate what the annual expenditure on smoke must be. The number of 7000 seems very large and is perhaps exaggerated. Round numbers are apt to be over rather than under the mark.

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.
