From Chapter 3:
It is uncertain when licences were first issued for the sale of tobacco. Probably they were issued in London some time before it was considered necessary to license dealers in other parts of the country. Among the Municipal Records of Exeter is the following note: "358. Whitehall, 31 August 1633. The Lords of the Council to the Chamber. 'Whereas his Ma^tie to prevent the excesse of the use of tobacco, and to set an order to those that regrate and sell or utter it by retayle, who observe noe reasonable rates or prizes [prices], nor take care that it be wholsome for men's bodyes that shall use it,' has caused letters to be sent to the chief Officers of Citties and towns requiring them to certify 'in what places it might be fitt to suffer ye retayleing of tobacco and how many be licenced in each of those places to use trade'; and the City of Exeter having made a return the Lords sent a list of those which are to be licensed, and order that no others be permitted to sell."

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."
