Jeremy L. Tackett, 19, was arrested at the jail Thursday by Deputy Mike Hall and charged with second-degree promoting contraband.
Hall alleges that Tackett hid two white Xanax pills in between a pair of white socks that he brought with him when he came to the jail.
Tackett pleaded guilty on March 28 to drug trafficking charges that stemmed from a November indictment.
He accepted a plea with the commonwealth attorney's office, which recommended a one-year sentence on a felony drug trafficking charge against him, and a 12-month sentence on a misdemeanor trafficking charge. The sentences will run concurrently, the plea agreement says.
Assistant Commonwealth's Attorney Wayne Taylor said Friday that the latest charge against Tackett, a misdemeanor which will be handled in district court, is punishable by a maximum of 12 months in jail.
Tackett may face "potential" problems, Taylor said, if he pleads guilty to the promoting contraband charge while on probation for the other drug trafficking charges against him. Such a plea could cause a violation of that probation, Taylor said, and cause a revocation of his parole.
"It may be in his best interest to plead to the promoting contraband charge immediately," he said.
Tackett is scheduled to be sentenced for the two trafficking charges on May 6.
