From Chapter 1:
The truth probably is that whoever actually smoked the first pipe, it was Raleigh who brought the practice into common use. It is highly probable, also, that Raleigh was initiated in the art of smoking by Thomas Hariot. This was made clear, I think, by the late Dr. Brushfield in the second of the valuable papers on matters connected with the life and achievements of Sir Walter, which he contributed under the title of "Raleghana" to the "Transactions" of the Devonshire Association. Hariot was sent out by Raleigh for the specific purpose of inquiring into and reporting upon the natural productions of Virginia. He returned in 1586, and in 1588 published the results of his researches in a thin quarto with an extremely long-winded title beginning "A briefe and true report of the new found land of Virginia" and continuing for a further 138 words.

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.
