From Chapter 4:
It is somewhat singular that the Puritans, who denounced most amusements and pleasures, and who frowned upon most of the occupations or diversions that make for gaiety and the enjoyment of life, did not, as Puritans, denounce the use of tobacco. One or two of their writers abused it roundly; but these were not representative of Puritan feeling on the subject. The explanation doubtless is that the practice of smoking was so very general and so much a matter of course among men of all ranks and of all opinions, that the mouths of Puritans were closed, so to speak, by their own pipes. A precisian, however, could take his tobacco with a difference. The seventeenth-century diarist, Abraham de la Pryme, says that he had heard of a Presbyterian minister who was so precise that "he would not as much as take a pipe of tobacco before that he had first sayed grace over it." George Wither, one of the most noteworthy of the poets who took the side of the Parliament, was confined in Newgate after the Restoration, and found comfort in his pipe.

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.
