CHARLOTTE, N.C. -- AJ Allmendinger tested positive for prescription Adderall, the suspended NASCAR driver told ESPN in an exclusive interview Tuesday.
Adderall is typically prescribed for attention deficit hyperactivity disorder, Allmendinger said. He does not have ADHD and therefore had no prescription.
He explained that he had been out in Louisville, Ky., the Wednesday before the Quaker State 400 race at Kentucky Speedway and was tired.
A friend of a friend, Allmendinger said, handed him a pill and stated it was a workout supplement that would give him energy. Allmendinger ingested the pill. Two days later he was randomly tested at the racetrack, a test he would ultimately fail.
He said neither NASCAR nor its drug testing team from Nashville-based Aegis Labs informed him of the specific substance in question until after a B sample was tested July 24, only that he had tested positive for an amphetamine. It was not until he was informed it was Adderall that he traced it back to that night in Kentucky.
Allmendinger said he does not abuse Adderall, rather that he took it just once.
Allmendinger is currently going through NASCAR's Road to Recovery program, which he said he hopes to complete by the end of August. He said his case is being treated more as a stress-coping methodology than drug rehabilitation.
A NASCAR official said NASCAR does not dispute Allmendinger's story, mainly because it is information the sanctioning body does not have. Spokesman David Higdon said NASCAR is unaware of the specific substance Allmendinger took, other than that it was an amphetamine. Higdon said testing won't reveal the brand of a substance.
"It's part of the Road to Recovery program, to discuss that and work through it," Higdon said. "We deal with [the individual] as soon as Dr. [David] Black comes back and recommends reinstantement."
