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 6:
John Philips, the author of "Cyder" and the "Splendid Shilling," was an undergraduate at Christ Church, during Aldrich's term of office, and no doubt learned to smoke in an atmosphere so favourable to tobacco. In his "Splendid Shilling," which dates from about 1700, Philips says of the happy man with a shilling in his pocket:

Meanwhile, he smokes, and laughs at merry tale,
Or Pun ambiguous or Conundrum quaint.
But the poor shillingless wretch can only
doze at home
In garret vile, and with a warming puff
Regale chill'd fingers; or from tube as black
As winter-chimney, or well-polish'd jet,
Exhale Mundungus, ill-perfuming scent.
>The miserable creature, though without a shilling, yet possessed a well-coloured "clay."

It is significant that the writer of a life of Philips, which was prefixed to an edition of his poems which was published in 1762, after mentioning that smoking was common at Oxford in the days of Aldrich, says apologetically, "It is no wonder therefore that he [Philips] fell in with the general taste ... he has descended to sing its praises in more than one place." By 1762, as we shall see, smoking was quite unfashionable, and consequently it was necessary to explain how it was that a poet could "descend" so low as to sing the praises of tobacco.
