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 plague was abroad even children were compelled to smoke. At the time of the dreadful visitation of 1665 all the boys at Eton were obliged to smoke in school every morning. One of these juvenile smokers, a certain Tom Rogers, years afterwards declared to Hearne, the Oxford antiquary, that he never was whipped so much in his life as he was one morning for not smoking. Times have changed at Eton since this anti-tobacconist martyr received his whipping. It is sometimes stated that at this time smoking was generally practised in schools, and that at a stated hour each morning lessons were laid aside, and masters and scholars alike produced their pipes and proceeded to smoke tobacco. But I know of no authority for this wider statement; it seems to have grown out of Hearne's record of the practice at Eton.
