From Chapter 1:
Who first smoked a pipe of tobacco in England? The honour is divided among several claimants. It has often been stated that Captain William Middleton or Myddelton (son of Richard Middleton, Governor of Denbigh Castle), a Captain Price and a Captain Koet were the first who smoked publicly in London, and that folk flocked from all parts to see them; and it is usually added that pipes were not then invented, so they smoked the twisted leaf, or cigars. This account first appeared in one of the volumes of Pennant's "Tour in Wales." But the late Professor Arber long ago pointed out that the remark as to the mode of smoking by cigars and not by pipes was simply Pennant's speculation. The authority for the rest of the story is a paper in the Sebright MSS., which, in an account of William Middleton, has the remark: "It is sayed, that he, with Captain Thomas Price of Plâsyollin and one Captain Koet, were the first who smoked, or (as they called it) drank tobacco publickly in London; and that the Londoners flocked from all parts to see them." No date is named, and no further particulars are available.

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.
