TABC license holders found to be violating the rule after Oct. 1 will have their license revoked, according to the rule. Greg Abbott ordered TABC and the Texas Department of State Health Services to ban sales of THC "to minors" and to require verification of ID of all customers attempting to buy the products. However, the TABC's rule does not encompass the entire landscape of retailers that sell the products. Owners and managers of smoke shops interviewed by The Texas Tribune said an age limit of 21 to purchase THC products is already being enforced by most distributors, so the regulations are not expected to be overly arduous.
