From Chapter 2:
Tobacco was smoked by all classes and in almost all places. It was smoked freely in the streets. In some verses prefixed to an edition of Skelton's "Elinour Rumming" which appeared in 1624, the ghost of Skelton, who was poet-laureate to King Henry VIII, was made to say that he constantly saw smoking:

As I walked between
Westminster Hall
And the Church of Saint Paul,
And so thorow the citie,
Where I saw and did pitty
My country men's cases,
With fiery-smoke faces,
Sucking and drinking
A filthie weede stinking.

Tobacco-selling was sometimes curiously combined with other trades. A Fleet Street tobacconist of this time was also a dealer in worsted stockings. A mercer of Mansfield who died at the beginning of 1624, and who apparently carried on business also at Southwell, had a considerable stock of tobacco. In the Inventory of all his "cattalles and goods" which is dated 24 January 1624, there is included "It. in Tobacco 19.li 0. 0." Nineteen pounds' worth of tobacco, considering the then value of money, was no small stock for a mercer-tobacconist to carry.

From Chapter 7:
Throughout the eighteenth century the use of tobacco for smoking was largely confined to the middle and humbler classes of society. To smoke was characteristic of the "cit," of the country squire, of the clergy (especially of the country parsons), and of those of lower social status. But at the same time it must be borne in mind that then, as since, the dictates of fashion and the conventions of society were little regarded by many artists and men of letters.

In the preceding chapter I quoted from Addison's diary of a retired tradesman in the Spectator of 1712. The periodical publications of a generation or so later paid the great essayist the flattery of imitation in this respect as in others. In the Connoisseur of George Colman and Bonnell Thornton, for instance, there is, in 1754, the description of a citizen's Sunday. The good man, having sent his family to church in the morning, goes off himself to Mother Redcap's, a favourite tavern—suburban in those days—or house of call for City tradesmen. There he smokes half a pipe and drinks a pint of ale. In the evening at another tavern he smokes a pipe and drinks two pints of cider, winding up the inane day at his club, where he smokes three pipes before coming home at twelve to go to bed and sleep soundly.
