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 7:
At Oxford in early Georgian days a profound calm—so far as study was concerned—appears to have prevailed. Little work was done, but much tobacco was smoked. In 1733 a satire was published, violently attacking the Fellows of various colleges. According to this satirist the occupation of the Magdalen Fellow was to
drink, look big,
Smoke much, think little, curse the freeborn Whig—

from which it may not unreasonably be surmised that the author was a Tory; and however little enthusiasm there may have been at Oxford in those days for learning and study, there was plenty of life in political animosities.

Another witness to the dons' love of tobacco is Thomas Warton. In his "Progress of Discontent," written in 1746, he plaintively sang:

Return, ye days when endless pleasure
I found in reading or in leisure!
When calm around the Common Room
I puff'd my daily pipe's perfume!
Rode for a stomach, and inspected,
At annual bottlings, corks selected:
And dined untax'd, untroubled, under
The portrait of our pious Founder!
