From Chapter 3:
The accomplished Shift promises a would-be pupil in the art of taking tobacco that if he pleases to be a practitioner, he shall learn in a fortnight to "take it plausibly in any ordinary, theatre, or the Tiltyard, if need be, in the most popular assembly that is." The Tiltyard adjoined Whitehall Palace and was the frequent scene of sports in which Queen Elizabeth took the greatest delight. Here took place, not only tilting properly so called, but rope-walking performances, bear- and bull-baiting, dancing and other diversions which her Majesty held in high favour. Consequently the Tiltyard was constantly the scene of courtly gatherings; and if smoking were permitted on such occasions—as Shift's boasting promises would appear to indicate—then it may be reasonably inferred that Queen Elizabeth did not entertain the objections to the new practice that her successor, King James, set forth with such vehemence in his famous "Counterblaste to Tobacco." There is, however, no positive evidence one way or the other, to show what the attitude of the Virgin Queen towards tobacco really was. A tradition as to her smoking herself on one occasion is referred to in a subsequent chapter—that on "smoking by Women."

From Chapter 6:
Other well-known men of the late seventeenth century were "tobacconists" in the old sense of the word. Sir Isaac Newton is said to have smoked immoderately; and a familiar anecdote represents him as using for the purposes of a tobacco-stopper, in a fit of absent-mindedness, the little finger of a lady sitting beside him, whom he admired, but the truth of this legend is open to doubt. Thomas Hobbes, who lived to be ninety (1588-1679), was accustomed to dine at 11 o'clock, after which he smoked a pipe and then lay down and took a nap of about half an hour. No doubt he would have attributed the length of his days to the regularity of his habits. Izaak Walton, who also lived to be ninety, as the lover of the placid and contemplative life deserved to do, loved his pipe, though he seldom mentions smoking in the "Compleat Angler." Sir Samuel Garth, poet and physician, once known to fame as the author of "The Dispensary," was another pipe-lover, as is shown by his verses quoted at the head of this chapter. Dudley, the fourth Lord North, began to smoke in 1657, and, says Dr. Jessopp, "the habit grew upon him, the frequent entries for pipes and tobacco showing that he became more and more addicted to this indulgence. Probably it afforded him some solace in the dreadful malady from which he suffered so long."
