From Chapter 4:
We know also that the Roundhead soldiers smoked in circumstances that did them no credit. In the account of the trial of Charles I, written by Dr. George Bates, principal physician to his Majesty, and to Charles II also, we read that when the sentence of the Court presided over by Bradshaw, condemning the King "to death by severing his Head from his Body," had been read, the soldiers treated the fallen monarch with great indignity and barbarity. They spat on his clothes as he passed by, and even in his face; and they "blew the smoak of tobacco, a thing which they knew his Majesty hated, in his sacred mouth, throwing their broken Pipes in his way as he passed along."

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.
