From Chapter 4:
But to turn from this worthy Exeter citizen to more famous names: I do not know of any good evidence as to whether or not Cromwell smoked, although he is said to have taken an occasional pipe while considering the offer of the crown, but John Milton certainly did. The account of how the blind poet passed his days, after his retirement from public office, was first told by his contemporary Richardson, and has since been repeated by all his biographers. His placid day ended early. The poet took his frugal supper at eight o'clock, and at nine, having smoked a pipe and drunk a glass of water, he went to bed. Apparently this modest allowance of a daily evening pipe was the extent of Milton's indulgence in tobacco. He knew nothing of what most smokers regard as the best pipe of the day—the after-breakfast pipe.

From Chapter 6:
Towards the close of the seventeenth century signs may be detected of some waning in the universal popularity of tobacco. There are hints of change in the records of City and other companies. Tobacco had always figured prominently in the provision for trade feasts. In 1651 the Chester Company of Barbers, Surgeons, Wax and Tallow Chandlers—a remarkably comprehensive organization—paid for "Sack beere and Tobacco" at the Talbot on St. Luke's Day, October 18, on the occasion of a dinner given to the Company by one Richard Walker; and similar expenditure was common among both London and provincial Companies. The court-books of the Skinners Company of London show that in preparation for their annual Election Dinner in 1694, the cook appeared before the court and produced a bill of fare which, with some alterations, was agreed to. The butler then appeared and undertook to provide knives, salt, pepper-pots, glasses, sauces, &c., "and everything needfull for £7. and if he gives content then to have £8. he provides all things but pipes, Tobacco, candles and beer"—which apparently fell to the lot of some other caterer.
