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:
Many of his followers smoked, sometimes apparently to such an extent as to cause scandal among their brethren. The following is an entry in the minutes of the Friends' Monthly Meeting at Hardshaw, Lancashire: "14th of 4th mo. 1691. It being considered that the too frequent use of smoking Tobacco is inconsistent with friends holy profession, it is desired that such as have occasion to make use thereof take it privately, neither too publicly in their own houses, nor by the highways, streets, or in alehouses or elsewhere, tending to the abetting the common excess." Another Lancashire Monthly Meeting, Penketh, under date "18th 8th mo. 1691" suggested that Friends were "not to smoke during their labour or occupation, but to leave their work and take it privately"—a suggestion which clearly proceeded from non-smokers. The smug propriety of these recommendations to enjoy a smoke in private is delightful.
