AJ Allmendinger tested positive for amphetamines.
Brand names of medications that contain or metabolize into amphetamines include Adderall, Dexedrine, Dextrostat, Desoxyn, Didrex, ProCentra and Vyvanse. Probably Adderall as this is used by many in the racing world. My source says Dinger did not have a prescription though
