Members of the hemp industry are suing Texas, claiming that the ban on hemp-derived THC products imposes an unconstitutional burden on interstate commerce. 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. "For more than seven years, Texans have built a multibillion-dollar hemp industry under laws that define these products as legal hemp. However, delta-9 THC, the most commonly sold THC product in Texas, will remain legal. Sen. Charles Perry, R-Lubbock, has already confirmed he will once again file a bill to ban consumable hemp products at the next legislative session.
