From Chapter 3:
Penalties for "offences" of this fanciful kind were not common in England; but in Puritan New England they were abundant. In the early days of the American Colonies the use of the "creature called Tobacko" was by no means encouraged. In Connecticut a man was permitted by the law to smoke once if he went on a journey of ten miles, but not more than once a day and by no means in another man's house. It could hardly have been difficult to evade so absurd a regulation as this.

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.
