From Chapter 2:
Hentzner, the German traveller, who visited London in 1598, speaks of smoking being customary among the audience at plays, who were also supplied with "fruits, such as apples, pears and nuts, according to the season, carried about to be sold, as well as ale and wine." He was struck with the universal prevalence of the tobacco-habit. Not only at plays, but "everywhere else," he says, the "English are constantly smoking tobacco," and then he proceeds to describe how they did it: "They have pipes on purpose made of clay, into the further end of which they put the herb, so dry that it may be rubbed into powder; and putting fire to it, they draw the smoak into their mouths, which they puff out again through their nostrils, like funnels, along with it plenty of phlegm and defluxions from the head." This suggests that the unpleasant and quite unnecessary habit of spitting was common with these early smokers, a suggestion which is amply supported by other contemporary evidence.

From Chapter Chapter 8:
Cowper then goes on to attack tobacco in lines which show how unpopular smoking at that date was with ladies, and which have since often been quoted by anti-tobacconists with grateful appreciation:

Pernicious weed! whose scent the fair annoys,
Unfriendly to society's chief joys,
Thy worst effect is banishing for hours
The sex whose presence civilizes ours;
Thou art indeed the drug a gardener wants,
To poison vermin that infest his plants,
But are we so to wit and beauty blind,
As to despise the glory of our kind,
And show the softest minds and fairest forms
As little mercy as the grubs and worms?

Notwithstanding this "satiric wipe," it is not likely that Cowper would have had much sympathy with John Wesley, who, in his detestation of what had been his father's solace at Epworth, forbade his preachers either to smoke or to take snuff.
