CHARLOTTE, N.C. (AP) -- Suspended NASCAR driver AJ Allmendinger tells ESPN he tested positive for a prescription drug usually used to treat attention deficit disorder.
Allmendinger says in an interview with ESPN that he took Adderall a couple of days before the race at Kentucky Speedway on June 30 because he was tired. He does not have ADHD or a prescription for the drug.
He says a friend gave him the pill and said it was a workout supplement that would give him energy.
Two days later he was randomly tested at the racetrack.
Allmendinger tells ESPN that he wasn't told what drug triggered the positive test, only that it was an amphetamine, until after a B sample was tested July 24.
Allmendinger says he had never taken the drug before.
