From Chapter 4:
In this country tobacco is said to have invaded even the House of Commons itself. Mr. J.H. Burn, in his "Descriptive Catalogue of London Tokens," writes: "About the middle of the seventeenth century it was ordered: That no member of the House do presume to smoke tobacco in the gallery or at the table of the House sitting as Committees." I do not know what the authority for this order may be, but there is no doubt that smoking was practised in the precincts of the House. In "Mercurius Pragmaticus," December 19-26, 1648, the writer says on December 20, speaking of the excluded members: "Col. Pride standing sentinell at the door, denyed entrance, and caused them to retreat into the Lobby where they used to drink ale and tobacco."

From Chapter 7:
At Oxford in early Georgian days a profound calm—so far as study was concerned—appears to have prevailed. Little work was done, but much tobacco was smoked. In 1733 a satire was published, violently attacking the Fellows of various colleges. According to this satirist the occupation of the Magdalen Fellow was to
drink, look big,
Smoke much, think little, curse the freeborn Whig—

from which it may not unreasonably be surmised that the author was a Tory; and however little enthusiasm there may have been at Oxford in those days for learning and study, there was plenty of life in political animosities.

Another witness to the dons' love of tobacco is Thomas Warton. In his "Progress of Discontent," written in 1746, he plaintively sang:

Return, ye days when endless pleasure
I found in reading or in leisure!
When calm around the Common Room
I puff'd my daily pipe's perfume!
Rode for a stomach, and inspected,
At annual bottlings, corks selected:
And dined untax'd, untroubled, under
The portrait of our pious Founder!
