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:
There is no mention of Parson Trulliber's pipe, but that pig-breeder and lover can hardly have been a non-smoker. Both the other clerical characters who appear in the book, the Roman Catholic priest who makes an equivocal appearance in the eighth chapter of the third book, and Parson Barnabas, who thinks that his own sermons are at least equal to Tillotson's, smoke their pipes. The other smokers in "Joseph Andrews" are the surgeon and the exciseman who, early in the story, are found sitting in the inn kitchen with Parson Barnabas, "smoking their pipes over some syderand"—the mysterious "cup" being a mixture of cider and something spirituous—and Joseph's father, old Gaffer Andrews, who appears at the end of the story, and complains bitterly that he wants his pipe, not having had a whiff that morning.
