From Chapter 1:
All the evidence agrees that whoever taught Raleigh, it was Raleigh's example that brought smoking into notice and common use. Long before his death in 1618 it had become fashionable, as we shall see, in all ranks of society. He is said to have smoked a pipe on the morning of his execution, before he went to the scaffold, a tradition which is quite credible.

From Chapter 5:
His Majesty was pleased, however, in a letter to Cambridge University, officially to condemn smoking by parsons, as at the same time he condemned the practice of wig-wearing and of sermon-reading by the clergy. But the royal frown was without effect. Wigs soon covered nearly every clerical head from the bench of bishops downwards; and it is very doubtful indeed whether a single parson put his pipe out.
