Lt. Governor Dan Patrick has made banning THC products a priority, calling them a "poison" and referring to his ban as a "life and death" matter. He's not backing off on this hellbent pursuit of a total ban but the lower house diluted his proposed bill a little.
In 2019 there was a bill passed that allowed for the commercialization of hemp that could include the un-removable non-intoxicating Delta 9 THC. Dan Patrick claims retailers made unregulated forms of THC available to the public.
