Colorado farmer Ryan Loflin made history last weekend by harvesting the nation's first commercial hemp crop in 56 years.
Hemp advocates said Loflin's harvest is a landmark event that could one day lead to larger-scale domestic farming of hemp for industrial uses such as food additives, cosmetics and building materials.
Hemp is genetically related to marijuana but contains only trace amounts of THC, the psychoactive substance that gets marijuana users high.
Loflin's 55-acre crop in southeastern Colorado's Baca County won't yield large amounts of hemp-seed oil and other by-products but is "quite significant symbolically," said Tom Murphy, national outreach coordinator for advocacy group Vote Hemp.
