From Chapter 2:
King James himself is an unwilling witness to the popularity of tobacco. He tells us that a man could not heartily welcome his friend without at once proposing a smoke. It had become, he says, a point of good-fellowship, and he that would refuse to take a pipe among his fellows was accounted "peevish and no good company." "Yea," he continues, with rising indignation, "the mistress cannot in a more mannerly kind entertain her servant than by giving him out of her fair hand a pipe of tobacco."

From Chapter 6:
There was clearly no prejudice against smoking at Cambridge. Abraham de la Pryme notes in his diary for the year 1694 that when it was rumoured in May of that year that a certain house opposite one of the colleges was haunted, strange noises being heard in it, several scholars of the college said, "Come, fetch us a good pitcher of ale, and tobacco and pipes, and wee'l sit up and see this spirit." The ale was duly provided, the pipes were lit, and the courageous smokers spent the night in the house, sitting "singing and drinking there till morning," but, alas! they neither saw nor heard anything.
