AUSTIN (KXAN) — In 2015, Texas approved the state’s limited marijuana law that allows patients to use products containing high levels of cannabidiol (CBD) and only trace levels of THC, but state officials are still working on how to regulate and figure out who can buy it and from where.

THC (Tetrahydrocannabinol) is the mind-altering ingredient found in cannabis. Many stores in Texas, like People’s Pharmacy, a holistic pharmacy headquartered in Austin, say they’re carrying the over-the-counter oil and following the law.

However, just a few days ago, the pharmacy’s owner, Bill Swail, says the Department of Public Safety came into his stores and demanded all the oil be removed from his shelves. He insists he’s following the law and his products have very low levels of THC.

Swail says DPS insisted they needed to take the oil to test it. He says law enforcement threatened to arrest him if he didn’t comply.

In a statement, DPS says they inspected and removed several items that they are testing for THC content. “No arrests were made and no additional action has been taken at this time.”

Sheila Hemphill with the Texas Hemp Industries Association says they are very appreciative of DPS’ involvement and are maintaining “very good, clear communication” with the agency. The organization says industrial hemp CBD products contain 0.3 percent or less THC. The legal threshold is 0.5 percent.

We reported earlier this month, that members of Texas’ Department of Public Safety Commission put off establishing the rules for the state’s limited medical marijuana law until their next meeting in October. DPS has to license three dispensing organizations by September first of next year.
