On Friday, two hemp retailers and a distributor filed a lawsuit in the U.S. District Court for the Southern District of Texas against the Texas Department of State Health Services; Attorney General Ken Paxton; and the Galveston County criminal district attorney and sheriff, alleging that classifying hemp-derived substances as illegal violates the 2018 Farm Bill, which removed it from the federal Controlled Substances Act.
