From Chapter 2:
Peers and squires and parsons and peasants alike smoked. The parson of Thornton, in Buckinghamshire, was so devoted to tobacco that when his supply of the weed ran short, he is said to have cut up the bell-ropes and smoked them! This is dated about 1630. In the well-known description of the famous country squire, Mr. Hastings, who was remarkable for keeping up old customs in the early years of the seventeenth century, we read of how his hall tables were littered with hawks' hoods, bells, old hats with their crowns thrust in, full of pheasants' eggs; tables, dice, cards, and store of tobacco-pipes.

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.
