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 6:
John Philips, the author of "Cyder" and the "Splendid Shilling," was an undergraduate at Christ Church, during Aldrich's term of office, and no doubt learned to smoke in an atmosphere so favourable to tobacco. In his "Splendid Shilling," which dates from about 1700, Philips says of the happy man with a shilling in his pocket:

Meanwhile, he smokes, and laughs at merry tale,
Or Pun ambiguous or Conundrum quaint.
But the poor shillingless wretch can only
doze at home
In garret vile, and with a warming puff
Regale chill'd fingers; or from tube as black
As winter-chimney, or well-polish'd jet,
Exhale Mundungus, ill-perfuming scent.
>The miserable creature, though without a shilling, yet possessed a well-coloured "clay."

It is significant that the writer of a life of Philips, which was prefixed to an edition of his poems which was published in 1762, after mentioning that smoking was common at Oxford in the days of Aldrich, says apologetically, "It is no wonder therefore that he [Philips] fell in with the general taste ... he has descended to sing its praises in more than one place." By 1762, as we shall see, smoking was quite unfashionable, and consequently it was necessary to explain how it was that a poet could "descend" so low as to sing the praises of tobacco.
