From Chapter 3:
The number of shops where tobacco was sold in the early days of its triumph seems to have been extraordinary. Barnaby Rich, one of the most prolific parents of pamphlets in an age of prolific writers, wrote a satire on "The Honestie of this Age," which was printed in 1614. In this production Rich declares that every fellow who came into an ale-house and called for his pot, must have his pipe also, for tobacco was then a commodity as much sold in every tavern, inn and ale-house as wine, ale, or beer. He goes on to say that apothecaries' shops, grocers' shops, and chandlers' shops were (almost) never without company who from morning to night were still taking tobacco; and what a number there are besides, he adds, "that doe keepe houses, set open shoppes, that have no other trade to live by but by the selling of tobacco." Rich says he had been told that a list had been recently made of all the houses that traded in tobacco in and near about London, and that if a man might believe what was confidently reported, there were found to be upwards of 7000 houses that lived by that trade; but he could not say whether the apothecaries', grocers' and chandlers' shops, where tobacco was also sold, were included in that number. He proceeds to calculate what the annual expenditure on smoke must be. The number of 7000 seems very large and is perhaps exaggerated. Round numbers are apt to be over rather than under the mark.

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.
