From Chapter 3:
It is pretty clear that not a few of the druggists who sold tobacco were great rascals. Ben Jonson has let us into some of their secrets of adulteration—the treatment of the leaf with oil and the lees of sack, the increase of its weight by other artificial additions to its moisture, washing it in muscadel and grains, keeping it in greased leather and oiled rags buried in gravel under ground, and by like devices. Other writers speak of black spice, galanga, aqua vitæ, Spanish wine, aniseeds and other things as being used for purposes of adulteration.

From Chapter 6:
Addison and Steele smoked, and so did Prior, who seems to have had a weakness at times for low company. After spending an evening with Oxford, Bolingbroke, Pope and Swift, it is recorded that he would go "and smoke a pipe, and drink a bottle of ale, with a common soldier and his wife, in Long Acre, before he went to bed." Some of Prior's poems, as Thackeray caustically remarks, smack not a little of the conversation of his Long Acre friends. Pope for awhile attended the symposium at Button's coffee-house, where Addison was the centre of the coterie—he describes himself as sitting with them till two in the morning over punch and Burgundy amid the fumes of tobacco—but such a way of life did not suit his sickly constitution, and he soon withdrew. It is not likely that he smoked.
