From Chapter 3:
One of the most curious of the early publications on tobacco, in which an attempt is made to hold the balance fairly between the legitimate use and the "licentious" abuse of the herb, is Tobias Venner's tract with the long-winded title: "A Brief and Accurate Treatise concerning The taking of the Fume of tobacco, Which very many, in these dayes doe too licenciously use. In which the immoderate, irregular, and unseasonable use thereof is reprehended, and the true nature and best manner of using it, perspicuously demonstrated." Venner described himself as a doctor of physic in Bath, and his tract was published in London in 1637. Venner says that tobacco is of "ineffable force" for the rapid healing of wounds, cuts, sores and so on, by external application, but thinks little of its use for any other purpose. Like others of his school, he attacks the "licentious Tobacconists [smokers] who spend and consume, not only their time, but also their health, wealth, and witts in taking of this loathsome and unsavorie fume." He admits the popularity of the herb, but expresses his own personal objection to the "detestable savour or smack that it leaveth behind upon the taking of it"; from which one is inclined to surmise that the doctor's first pipe was not an entire success. With an evident desire to be fair, Venner, notwithstanding his dislike of the "savour," refuses to condemn tobacco utterly, because of what he considers its valuable medicinal qualities, and he goes so far as to give "10 precepts in the use of" tobacco. The sixth is "that you drink not between the taking of the fumes, as our idle and smoakie Tobacconists are wont"—there must be no alliance, in short, between the pipe and the cheerful glass. The tenth and last precept is "that you goe not abroad into the aire presently [immediately] upon the taking of the fume, but rather refrain therefrom the space of halfe an houre, or more, especially if the season be cold, or moist." The suggestion that the smoker, when he has finished his pipe, shall wait for half an hour or so before he ventures into the outer air is very quaint.

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.
