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 8:
Parr is said on one occasion to have called for a pipe after taking a meal at a coaching-inn called the "Bush" at Bristol, when the waiter told him that smoking was not allowed at the Bush. Parr persisted, but the authorities at the inn were firm in their refusal to allow anything so vulgar as smoking on their premises, whereupon Parr is said to have exclaimed: "Why, man, I've smoked in the dining-room of every nobleman in England. The Duchess of Devonshire said I could smoke in every room in her house but her dressing-room, and here, in this dirty public-house of Bristol you forbid smoking! Amazing! Bring me my bill." The learned doctor exaggerated no doubt as regards the facilities given him for smoking; for it was his overbearing way not to ask for leave to smoke, but to smoke wherever he went, whether invited to do so or not; but the story shows the prejudice against smoking which was found in many places as a result of the attitude of the fashionable world towards tobacco.
