From Chapter 3:
The druggists and other tradesmen who sold tobacco in Elizabethan and Jacobean days had every provision for the convenience of their numerous customers. Some so-called druggists, it may be shrewdly suspected, did much more business in tobacco than they did in drugs. Dekker tells us of an apothecary and his wife who had no customers resorting to their shop "for any phisicall stuffe," but whose shop had many frequenters in the shape of gentlemen who "came to take their pipes of the divine smoake." That tobacco was often the most profitable part of a druggist's stock is also clear from the last sentence in Bishop Earle's character of "A Tobacco-Seller," one of the shortest in that remarkable collection of "Characters" which the Bishop issued in 1628 under the title of "Micro-Cosmographie."

From Chapter 8:
In the first two or three decades of the nineteenth century smoking reached its nadir. No dandy smoked. If some witnesses may be believed smoking had almost died out even at Oxford. Archdeacon Denison wrote in his "Memories"—"When I went up to Oxford, 1823-24, there were two things unknown in Christ Church, and I believe very generally in Oxford—smoking and slang"; but one cannot help fancying that the archdeacon's memory was not quite trustworthy. It is difficult to imagine that there was ever a time when the slang of the day was not current on the lips of young Oxford, or that so long as tobacco was procurable it did not find its way into college rooms.
