From Chapter 2:
smoking was not confined to the auditors on the stage, who paid sixpence each for a stool. There was the "lords' room" over the stage, which seems to have corresponded with the modern stage boxes, the price of admission to which appears to have been a shilling, where the pipe was also in full blast. Dekker tells how a gallant at a new play would take a place in the "twelve penny room, next the stage, because the lords and you may seem to be hail fellow, well met"; and Jonson, in "Every Man out of his Humour," 1600, speaks of one who pretended familiarity with courtiers, that he talked of them as if he had "taken tobacco with them over the stage, in the lords' room."

From Chapter 8:
If smoking had died out at Oxford its decline must have been rapid. When a certain young John James was an undergraduate of Queen's, 1778 to 1781, he and his correspondents spoke severely of the "miserable condition of Fellows who (under the liberal pretence of educating youth) spend half their lives in smoking tobacco and reading the newspapers." About 1800 the older or more old-fashioned of the Fellows at New College, "not liking the then newly introduced luxury of Turkey carpets," says Mr. G.V. Cox, in his "Recollections of Oxford," 1868, "often adjourned to smoke their pipe in a little room opposite to the Senior Common-room, now appropriated to other uses, but then kept as a smoking-room." A Mr. Rhodes, a one-time Fellow of Worcester College, who was elected Esquire Bedel in Medicine and Arts in 1792, had a very peculiar way of enjoying his tobacco. Mr. Cox says: "On one occasion, when I had to call upon him, I found him drinking rum and water, and enjoying (what he called his luxury) the fumes of tobacco, not through a pipe or in the shape of a cigar, but burnt in a dish!"
