From Chapter 4:
In this "Diary," covering the years 1631-43, there are some forty entries concerning the purchase of what is always, save in one case, called "tobacka." These entries give valuable information as to the prices of the two chief kinds of tobacco. One was imported from Spanish America, which up to 1639 Hayne calls "Varinaes," and after that date "Spanish"; the other was imported from English colonies—chiefly from Virginia. The "Varinaes" kind, Dr. Brushfield suggests, was obtained from Varina, near the foot of the range of mountains forming the west boundary of Venezuela, and watered by a branch of the Orinoco River. Hayne also notes the purchase of "Tertudoes" tobacco, but what that may have been I cannot say. From the various entries relating respectively to Varinaes or Spanish tobacco, and to Virginia tobacco, it is clear that the former ranged in price from 8s. to 13s. per lb., while the latter was from 1s. 6d. to 4s. per lb. There is one entry of "perfumed Tobacka," 10 oz. of which were bought at the very high price of 15s. 6d.

From Chapter 5:
The belief in the prophylactic power of tobacco was, however, very generally held. When Mr. Samuel Pepys on June 7, 1665, for the first time saw several houses marked with the ominous red cross, and the words "Lord, have mercy upon us" chalked upon the doors, he felt so ill at ease that he was obliged to buy some roll tobacco to smell and chew. There is nothing to show that Pepys even smoked, which considering his proficiency in the arts of good-fellowship, is perhaps a little surprising. Defoe, in his fictitious but graphic "Journal of the Plague Year in London," says that the sexton of one of the London parishes, who personally handled a large number of the victims, never had the distemper at all, but lived about twenty years after it, and was sexton of the parish to the time of his death. This man, according to Defoe, "never used any preservative against the infection other than holding garlic and rue in his mouth, and smoking tobacco."
