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:
Even the staid Quakers smoked. George Fox's position in regard to tobacco was curious. He did not smoke himself; but on one occasion he was offered a pipe by a jesting youth who thought thereby to shock so saintly a person. Fox says in his "Journal," "I lookt upon him to bee a forwarde bolde lad: and tobacco I did not take: butt ... I saw hee had a flashy empty notion of religion: soe I took his pipe and putt it to my mouth and gave it to him again to stoppe him lest his rude tongue should say I had not unity with ye creation." The incident is curious, but testifies to Fox's tolerance and breadth of outlook.
