From Chapter 2:
Tobacco engages
Both sexes, all ages,
The poor as well as the wealthy;
From the court to the cottage,
From childhood to dotage,
Both those that are sick and the healthy.

This chapter and the next deal with the history of smoking during the first fifty years after its introduction as a social habit—roughly to 1630.

The use of tobacco spread with extraordinary rapidity among all classes of society. During the latter part of Queen Elizabeth's reign and through the early decades of the seventeenth century tobacco-pipes were in full blast. Tobacco was triumphant.

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.
