In these circumstances, Sandys necessarily devoted his main energies after 1621 to the problem of tobacco, the only marketable staple the colony had as yet produced. It was an old problem, but one now filled with new difficulties. In earlier days, when it had been hoped that tobacco might be one of a variety of staples produced in the colony, the Virginia Company, like the Bermuda Company, had lent encouragement to efforts looking to its production. But hardly had early experiments proved successful before the adventurers faced the risk that tobacco would take over the colony entirely. There is nothing surprising in this development, for a tobacco plant, unlike a grapevine or an olive tree, matures within a few months of its planting, and the tobacco habit at this time was a thing of comparably rapid growth in many parts of the world. To settlers who had been staked by adventurers ever insistent upon a prompt return of their capital, or who wondered how best to procure the means to make payment for the supplies brought in the next magazine ship, the obvious answer was to plant the land to tobacco. After doing this, if time and energy remained, they might try some of Sir Edwin Sandys' ideas--maybe set out a few grapevines or mulberries, as they had been instructed to do. There was good reason for the growing fear among the leading adventurers in London that tobacco might put a blight on all other projects. More than that, the increasing shipments of tobacco, especially in view of the still relatively poor quality of the Virginia leaf, gave the colony a bad name just when its good name was so important to the promotional efforts of the company. The tobacco habit did not yet have the respectable associations it would later acquire in the eighteenth century. Instead, it was associated with tippling or bawdy houses, where in truth a pipe was most easily had by the contemporary resident of London. Moral considerations were reinforced by an additional concern for the public interest. So much of the weed consumed came from Spain that thoughtful men were inclined to consider how much England paid out, to the profit of the Spaniard, for a commodity which added nothing to the well being of the country. Had it not been for the influence of Virginia and Bermuda adventurers in the House of Commons, Parliament in 1621 might well have prohibited all importation of tobacco into England. And in all England there was no more vigorous opponent of tobacco than the king himself. Indeed, the king had even written a book on the subject.
