From Chapter 3:
"A Tobacco-Seller," says Earle, "is the onely man that findes good in it which others brag of, but do not; for it is meate, drinke, and clothes to him. No man opens his ware with greater seriousnesse, or challenges your judgement more in the approbation. His shop is the Randevous of spitting, where men dialogue with their noses, and their communication is smoake. It is the place onely where Spaine is commended, and prefer'd before England itselfe. He should be well experienc'd in the world: for he ha's daily tryall of mens nostrils, and none is better acquainted with humors. Hee is the piecing commonly of some other trade which is bawde to his Tobacco, and that to his wife, which is the flame that follows this smoke."

From Chapter 6:
But so early as 1655 there is a sign of change of custom—a change, that is, in the direction of restricting and limiting the hitherto unbounded freedom granted to the use of tobacco. The London Society of Apothecaries on August 15, 1655, held a meeting for the election of a Master and an Upper Warden; and from the minutes of this meeting we learn that by general consent it was forbidden henceforward to smoke in the Court Room while dining or sitting, under penalty of half a crown.
