Three members of the hemp industry are suing the state of Texas for violating commerce protections after it was announced last week that nearly all hemp-derived THC products are illegal.

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.

The complaint states that the reinstated definitions provide no delineation between lawful hemp and unlawful marijuana; that it's preempted by the 2018 Farm Bill's protections for the interstate hemp market; and that these classifications impose an unconstitutional burden on interstate commerce.
