President Donald Trump today signed legislation into law that includes language lifting the United States’ decades-long prohibition on domestic, commercial hemp production. The provisions were included within The Agriculture Improvement Act of 2018 (aka ‘The Farm Bill’), which takes effect on January 1, 2019. “The significance of this law change should not be underemphasized,” NORML Deputy Director Paul Armentano said. “This law marks the first change in the federal classification of the cannabis plant since it was initially classified as a schedule I controlled substance by Congress in 1970, and paves the way for the first federally-sanctioned commercial hemp grows since World War II.” Language included in the 2014 version of the Farm Bill ( Sec. 7606 ) permitted states to license farmers to cultivate hemp as part of a university-sanction pilot program, but did not allow for the commercialization of the crop.
