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:
Grave wits, who, spending farthings four,
Sit, smoke, and warm themselves an hour.

The allusions in the Spectator to smoking in the coffee-houses are frequent. "Sometimes," says Addison, in his title character in the first number of the paper, "sometimes I smoak a pipe at Child's and whilst I seem attentive to nothing but the Post-man, over-hear the conversation of every table in the room." And here is a vignette of coffee-house life in 1714 from No. 568 of the Spectator: "I was yesterday in a coffee-house not far from the Royal Exchange, where I observed three persons in close conference over a pipe of tobacco; upon which, having filled one for my own use, I lighted it at the little wax candle that stood before them; and after having thrown in two or three whiffs amongst them, sat down and made one of the company. I need not tell my reader, that lighting a man's pipe at the same candle is looked upon among brother-smoakers as an overture to conversation and friendship." From the very beginning smoking has induced and fostered a spirit of comradeship.
