From Chapter 1:
King James, in his reference to the "first Author" of what he calls "this abuse," clearly had Sir Walter Raleigh in view, and it is Raleigh with whom in the popular mind the first pipe of tobacco smoked in England is usually associated. The tradition is crystallized in the story of the schoolboy who, being asked "What do you know about Sir Walter Raleigh?" replied: "Sir Walter Raleigh introduced tobacco into England, and when smoking it in this country said to his servant, 'Master Ridley, we are to-day lighting a candle in England which by God's blessing will never be put out'"!

From Chapter 8:
In the first two or three decades of the nineteenth century smoking reached its nadir. No dandy smoked. If some witnesses may be believed smoking had almost died out even at Oxford. Archdeacon Denison wrote in his "Memories"—"When I went up to Oxford, 1823-24, there were two things unknown in Christ Church, and I believe very generally in Oxford—smoking and slang"; but one cannot help fancying that the archdeacon's memory was not quite trustworthy. It is difficult to imagine that there was ever a time when the slang of the day was not current on the lips of young Oxford, or that so long as tobacco was procurable it did not find its way into college rooms.
