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 5:
His Majesty was pleased, however, in a letter to Cambridge University, officially to condemn smoking by parsons, as at the same time he condemned the practice of wig-wearing and of sermon-reading by the clergy. But the royal frown was without effect. Wigs soon covered nearly every clerical head from the bench of bishops downwards; and it is very doubtful indeed whether a single parson put his pipe out.
