US hemp food sales have increased by at least 47% since the American Hemp Industries Association stopped the government's Drug Enforcement Administration from banning the foods.

Sales grew to $4.57million for the year ending July 2005 after the government's case ceased, spurring surges in supply and consumption. Hemp seed is not psychoactive, and some legislators want to bring back hemp farming to the country.

Currently, seeds grown and processed abroad supply the US marketplace. According to the HIA, Americans are demanding healthy sources of omega-3 to supplement their diets as an alternative to fish due to trace mercury concerns. Hemp seed is very rich in essential fatty acids and second only to soybeans in complete protein.
