From Chapter 2:
A curious feature of tobacco-manners among fashionable smokers of the period was the practice of passing a pipe from one to another, after the fashion of the "loving cup." There is a scene in "Greene's Tu Quoque," 1614, laid in a fashionable ordinary, where the London gallants meet as usual, and one says to a companion who is smoking: "Please you to impart your smoke?" "Very willingly, sir," says the smoker. Number two takes a whiff or two and courteously says: "In good faith, a pipe of excellent vapour!" The owner of the pipe then explains that it is "the best the house yields," whereupon the other immediately depreciates it, saying affectedly: "Had you it in the house? I thought it had been your own: 'tis not so good now as I took it for!" Another writer of this time speaks of one pipe of tobacco sufficing "three or four men at once."

From Chapter 7:
It seems to have been taken for granted that country parsons smoked. smoking was universal among their male parishioners from the squire to the labourer (when he could afford it), so that it was only natural that the parson, with little to do, and in those days not too much inclination to do it, should be as fond of his pipe as the rest of the world around him. In a World of 1756 there is an account of a country gentleman entertaining one evening the vicar of the parish, and the host as a matter of course proceeds to order a bottle of wine with pipes and tobacco to be placed on the table. The vicar forthwith "filled his pipe, and drank very cordially to my friend," his host. One cannot doubt that Laurence Sterne, that most remarkable of country parsons, smoked. His "My Uncle Toby" is among the immortals, and Toby without his pipe is unimaginable.
