The Spaniards brought hemp to the Americas and cultivated it in Chile starting about 1545. Similar attempts were made in Peru, Colombia, and Mexico, but only in Chile did the crop find success. In July 1605, Samuel Champlain reported the use of grass and hemp clothing by the (Wampanoag) people of Cape Cod and the (Nauset) people of Plymouth Bay told him they harvested hemp in their region where it grew wild to a height of 4 to 5 ft.  In May 1607, "hempe" was among the crops Gabriel Archer observed being cultivated by the natives at the main Powhatan village, where Richmond, Virginia is now situated; and in 1613, Samuell Argall reported wild hemp "better than that in England" growing along the shores of the upper Potomac. As early as 1619, the first Virginia House of Burgesses passed an Act requiring all planters in Virginia to sow "both English and Indian" hemp on their plantations. The Puritans are first known to have cultivated hemp in New England in 1645.
With 78% essential fats hemp oil greatly exceeds soy oil at 40%, canola oil at 30%, olive oil at 10% and other oils. Omega 3 and Omega 6 essential fats may reduce cholesterol, blood pressure, coronary heart disease and stroke. The 3:1 ratio of Omega 6 to Omega 3 EFA's in hemp oil is thought to be the best in nature for promoting cellular health. Hemp oil contains more "Omega 3" EFA components (19%) than are found in any fish and in most fish-oil supplements.
As of December 2018, Hemp is federally legal to grow again in the United States. The government passed the Hemp Farming Act of 2018, part of the 2018 Farm Bill signed by President Donald Trump on 20 December 2018. This bill changed hemp from a controlled substance to an agricultural commodity, legalizing hemp federally, which made it easier for farmers to get production licenses, get loans to grow hemp, and allowed them to get federal crop insurance. Some states still consider it illegal to grow hemp, but 41 states have begun the process to make hemp legal to grow at the state level, as of 2019.

While the Marihuana Tax Act of 1937 had just been signed into law, the United States Department of Agriculture lifted the tax on hemp cultivation during WW II. Before WW II, the U.S. Navy used Jute and Manila Hemp from the Philippines and Indonesia for the cordage on their ships. During the war, Japan cut off those supply lines. America was forced to turn inward and revitalize the cultivation of Hemp on U.S. soils.
Hemp seeds, or hemp hearts, are the seeds of the hemp plant, Cannabis sativa. Technically a nut, these small, crunchy seeds are safe to consume and contain only traces of a psychotropic chemical, called THC, the primary psychoactive compound in cannabis which is known to cause euphoria. These seeds have a soft, creamy filling which has a mild, nutty flavor, and they are usually eaten raw.
