From Chapter 2:
Queen Elizabeth's Secretary of State, Sir Robert Cecil, would appear to have been a smoker. In a letter addressed to him, John Watts, an alderman of London, wrote: "According to your request, I have sent the greatest part of my store of tobaca by the bearer, wishing that the same may be to your good liking. But this tobaca I have had this six months, which was such as my son brought home, but since that time I have had none. At this period there is none that is good to be had for money. Wishing you to make store thereof, for I do not know where to have the like, I have sent you of two sorts. Mincing Lane, 12 Dec. 1600."

From Chapter 6:
Addison and Steele smoked, and so did Prior, who seems to have had a weakness at times for low company. After spending an evening with Oxford, Bolingbroke, Pope and Swift, it is recorded that he would go "and smoke a pipe, and drink a bottle of ale, with a common soldier and his wife, in Long Acre, before he went to bed." Some of Prior's poems, as Thackeray caustically remarks, smack not a little of the conversation of his Long Acre friends. Pope for awhile attended the symposium at Button's coffee-house, where Addison was the centre of the coterie—he describes himself as sitting with them till two in the morning over punch and Burgundy amid the fumes of tobacco—but such a way of life did not suit his sickly constitution, and he soon withdrew. It is not likely that he smoked.
