Following the depression of 1639 tobacco prices failed to rise above three pence, and probably never averaged more than two pence per pound for the next sixty years. To prevent the complete ruination of the tobacco planters, the General Assembly established fixed rates for tobacco in the payment of certain fees. In 1645 these fees were payable in tobacco rated at one and one-half pence per pound; ten years later the rate had increased only a half pence. The war with Holland, restrictions on the Dutch trade, and the plague in England brought forth another serious depression in the colonies in the 1660's. In 1665 the tobacco fleet did not go to the colonies on account of the plague in London. Tobacco prices dropped to one pence per pound.

In 1662 the Assembly prohibited the planting of tobacco after the last of June, provided that Maryland would do the same. Maryland rejected the idea. This would have eliminated a great deal of inferior tobacco, for much of the tobacco planted in July seldom fully matures before it must be harvested to save it from the frost. The planters in both colonies continued to produce excessive crops and the depression became more acute. Led by Virginia, the North Carolina and Maryland legislatures prohibited the cultivation of tobacco in 1666. Lord Baltimore again refused to permit a cessation in Maryland, consequently Virginia and North Carolina repealed their legislation. Instead of cessation the Virginia crop was so large in 1666 that 100 vessels were not enough to export the crop. The possibility of another enormous crop in 1667 was eliminated by a severe storm that destroyed two-thirds of the crop. However, the glutted market resulting from the large crop grown in 1666 caused prices to fall to a half pence per pound.
