From Chapter 4:
From the various entries in the "Diary" relating to the purchase of tobacco, it seems clear that there was no shop in Exeter devoted specially or exclusively to the sale of the weed. Hayne bought his supplies from four of the leading goldsmiths of the city, who can be identified by the fact that he had dealings with them in their own special wares, also from two drapers, one grocer, and four other tradesmen (on a single occasion each) whose particular occupations are unknown.

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.).
