Couch had a “weak positive” on a monitoring drug patch, said the Tarrant County District Attorney’s Office said in a written statement.
The DA said the probation department “did not have confidence in the result.”
The arrest warrant issued Thursday claimed the patch detected Tetrahydrocannabinol (THC) in Couch’s system. THC is the ingredient in marijuana that causes a high.
Tarrant County authorities are going to conduct additional testing to determine whether the “weak positive” was due to legal CBD oil usage or marijuana. If there is proof that Couch used illegal drugs, the DA’s office will file a motion to revoke his probation.
