From Chapter 2:
smoking was soon as common in the country as in London. On Wednesday, April 16, 1621, in the course of a debate in the House of Commons, Sir William Stroud, who seems to have been a worthy disciple of that tobacco-hater, King James I, moved that he "would have tobacco banished wholly out of the kingdom, and that it may not be brought in from any part, nor used amongst us"; and Sir Grey Palmes said "that if tobacco be not banished, it will overthrow 100,000 men in England, for now it is so common that he hath seen ploughmen take it as they are at plough." Perhaps this terrible picture of a ploughman smoking as he followed his lonely furrow did not impress the House so much as Sir Grey evidently thought it would; at all events, tobacco was not banished.

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.).
