From Chapter 4:
It is somewhat singular that the Puritans, who denounced most amusements and pleasures, and who frowned upon most of the occupations or diversions that make for gaiety and the enjoyment of life, did not, as Puritans, denounce the use of tobacco. One or two of their writers abused it roundly; but these were not representative of Puritan feeling on the subject. The explanation doubtless is that the practice of smoking was so very general and so much a matter of course among men of all ranks and of all opinions, that the mouths of Puritans were closed, so to speak, by their own pipes. A precisian, however, could take his tobacco with a difference. The seventeenth-century diarist, Abraham de la Pryme, says that he had heard of a Presbyterian minister who was so precise that "he would not as much as take a pipe of tobacco before that he had first sayed grace over it." George Wither, one of the most noteworthy of the poets who took the side of the Parliament, was confined in Newgate after the Restoration, and found comfort in his pipe.

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.
