What is Industrial Hemp?
Industrial hemp (Cannabis sativa L.) was grown as a commodity fiber crop in the United States from the mid-18th century until the mid-1930s. As in many other countries, C. sativa was banned and was considered an illegal crop in the U.S. for several decades.
In 2014, Section 7606 of the federal Agricultural Act of 2014, commonly called the Farm Bill, allowed the cultivation of industrial hemp within authorized pilot programs for “the plant Cannabis sativa L. and any part of such plant, whether growing or not, with a delta-9 tetrahydrocannabinol [THC] concentration of not more than 0.3 percent on a dry weight basis.”
