From Chapter 1:
It may further be added that though the use of tobacco was known and practised on the continent of Europe for some time before smoking became common in England—it was taken to Spain from Mexico by a physician about 1560, and Jean Nicot about the same time sent tobacco seeds to France—yet such use was exclusively for medicinal purposes. The smoking of tobacco in England seems from the first to have been much more a matter of pleasure than of hygiene.

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.
