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 5:
When excavations were in progress early in 1901, preparatory to the construction of Kingsway and Aldwych, they included the removal of bodies from the burying-grounds of St. Clement Danes and St. Mary-le-Strand; and among the bones were found a couple of the curious tobacco-pipes called "plague-pipes," because they are supposed to have been used as a protection against infection by those whose office it was to bury the dead. These pipes have been dug up from time to time in numbers so large that one antiquary, Mr. H. Syer Cuming, has ventured to infer that "almost every person who ventured from home invoked the protection of tobacco."
