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 7:
The London clergy seem to have smoked at one time as a matter of course at their gatherings at Sion College, their headquarters. An entry in the records under date February 14, 1682, relating to a Court Meeting, runs: "Paid Maddocks [the Messenger] for Attendinge and Pipes 6d." How long pipes continued to be concomitants of the meetings of the College's General Court I cannot say; but smoking and the annual dinners were long associated. At the anniversary feast in 1743 there were two tables to provide for, the total number of guests being about thirty, and two "corses" to each. The cost of the food, as Canon Pearce tells us in his excellent and entertaining book on the College and its Library, was £19 15s., or rather more than 13s. a head. The bill for wines and tobacco amounted to five guineas, or about 3s. 6d. a head, and for this modest sum the thirty convives enjoyed eleven gallons of "Red Oporto," one of "White Lisbon," and three of "Mountain," to the accompaniment of two pounds of tobacco (at 3s. 4d. the pound) smoked in "half a groce of pipes" (at 1s.).
