From Chapter 4:
Some of the Puritan colonists in America took a strong line on the subject. Under the famous "Blue Laws" of 1650 it was ordered by the General Court of Connecticut that no one under twenty-one was to smoke—"nor any other that hath not already accustomed himself to the use thereof." And no smoker could enjoy his pipe unless he obtained a doctor's certificate that tobacco would be "usefull for him, and allso that he hath received a lycense from the Courte for the same." But the unhappy smoker having passed the doctor and obtained his licence was still harassed by restrictions, for it was ordered that no man within the colony, after the publication of the order, should take any tobacco publicly "in the streett, highwayes, or any barn-yardes, or uppon training dayes, in any open places, under the penalty of six-pence for each offence against this order." The ingenuities of petty tyranny are ineffable. It is said that these "Blue Laws" are not authentic; but if they are not literally true, they are certainly well invented, for most of them can be paralleled and illustrated by laws and regulations of undoubted authenticity.

From Chapter 8:
If smoking had died out at Oxford its decline must have been rapid. When a certain young John James was an undergraduate of Queen's, 1778 to 1781, he and his correspondents spoke severely of the "miserable condition of Fellows who (under the liberal pretence of educating youth) spend half their lives in smoking tobacco and reading the newspapers." About 1800 the older or more old-fashioned of the Fellows at New College, "not liking the then newly introduced luxury of Turkey carpets," says Mr. G.V. Cox, in his "Recollections of Oxford," 1868, "often adjourned to smoke their pipe in a little room opposite to the Senior Common-room, now appropriated to other uses, but then kept as a smoking-room." A Mr. Rhodes, a one-time Fellow of Worcester College, who was elected Esquire Bedel in Medicine and Arts in 1792, had a very peculiar way of enjoying his tobacco. Mr. Cox says: "On one occasion, when I had to call upon him, I found him drinking rum and water, and enjoying (what he called his luxury) the fumes of tobacco, not through a pipe or in the shape of a cigar, but burnt in a dish!"
