AUSTIN (KXAN) — Hemp Cannabidiol (CBD) products confiscated from four Austin pharmacies in September have been found to contain no detectable amounts of THC. Based on the results, the Department of Public Safety says they will not pursue any enforcement action.

THC (Tetrahydrocannabinol) is the mind-altering ingredient found in cannabis. On Sept. 7, DPS arrived at four People’s Pharmacy locations and confiscated various industrial hemp products.

Pharmacy owner Bill Swail says before the products were confiscated, DPS came into the store and demanded all the hemp oil be removed from the shelves. Sheila Hemphill with the Texas Hemp Industries Association said at the time industrial hemp contains 0.3 percent or less THC. The legal threshold is 0.5 percent.

Hemphill says she’s aware of seven conflicts with law enforcement since January 2016 and that none have resulted in a conviction. “Ambiguity in the law related to the status of CBD under the TCSA has caused general confusion, unnecessary expenditures by law enforcement, legal expenses and untold stress to innocent consumers and businesses,” Hemphill explained.

“This event with People’s pharmacy demonstrates the necessity for our upcoming Texas Legislature to define industrial hemp as an agriculture crop separate from the marijuana definition in the CSA.”

Low-level THC oil sales have soared in the state in recent months. Many customers are veterans or elderly — people who suffer from chronic pain, anxiety and epilepsy.
