From Chapter 1:
In this "Report" Hariot says of the tobacco plant: "There is an herbe which is sowed a part by itselfe and is called by the inhabitants Vppówoc: In the West Indies it hath divers names, according to the severall places and countries where it groweth and is used: The Spaniardes generally call it Tobacco. The leaves thereof being dried and brought into powder: they use to take the fume or smoke thereof by sucking it through pipes made of claie into their stomacke and heade: from whence it purgeth superfluous fleame and other grosse humors, openeth all the pores and passages of the body: by which meanes the use thereof, not only preserveth the body from obstructions: but if also any be, so that they have not beane of too long continuance, in short time breaketh them: wherby their bodies are notably preserved in health, and know not many greevous diseases wherewithall wee in England are oftentimes afflicted."

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.
