From Chapter 1:
In this "Report" Hariot says of the tobacco plant: "There is an herbe which is sowed a part by itselfe and is called by the inhabitants Vppówoc: In the West Indies it hath divers names, according to the severall places and countries where it groweth and is used: The Spaniardes generally call it Tobacco. The leaves thereof being dried and brought into powder: they use to take the fume or smoke thereof by sucking it through pipes made of claie into their stomacke and heade: from whence it purgeth superfluous fleame and other grosse humors, openeth all the pores and passages of the body: by which meanes the use thereof, not only preserveth the body from obstructions: but if also any be, so that they have not beane of too long continuance, in short time breaketh them: wherby their bodies are notably preserved in health, and know not many greevous diseases wherewithall wee in England are oftentimes afflicted."

From Chapter 7:
In a World of 1755 there is a description of a noisy, hearty, drinking, devil-may-care country gentleman, in which it is said, "he makes no scruple to take his pipe and pot at an alehouse with the very dregs of the people." In a Connoisseur of 1754 a fine gentleman from London, making a visit in a country-house, is taking his breakfast with the ladies in the afternoon, when they had their tea, for, says he, "I should infallibly have perished, had I staied in the hall, amidst the jargon of toasts and the fumes of tobacco." When Horace Walpole was staying with his father at his Norfolk country-seat, Houghton, in September 1737, Gray wrote to him from Cambridge: "You are in a confusion of wine, and roaring, and hunting, and tobacco, and, heaven be praised, you too can pretty well bear it." But Gray had no objection to tobacco. He lived at Cambridge, and the dons and residents there (as at Oxford), not to speak of the undergraduates, were as partial to their pipes as the men who went out from among them to become country parsons, and to share the country squire's liking for tobacco. Gray wrote to Warton from Cambridge in April 1749 saying: "Time will settle my conscience, time will reconcile me to this languid companion (ennui); we shall smoke, we shall tipple, we shall doze together"—a striking picture of University life in the sleepy days of the eighteenth century. Gray's testimony by no means stands alone. In November 1730 Roger North wrote to his son Montague, then an undergraduate at Cambridge, saying: "I would be loath you should confirm the scandal charged upon the universities of learning chiefly to smoke and to drink."
