Doping is making waves in Nascar

Following the Mayfield affair. The pilot of Nascar Ryan Newman wants to know which drugs are capable of being detected and designated as doping products. As a reminder, Jeremy Mayfield, Nascar driver in the Sprint Cup, was suspended indefinitely following the detection of a prohibited product, not communicated, during an unannounced test. The pilot said his positive test came after he was prescribed prescription drugs. Challenged by Mayfield's good faith, Newman therefore wants to be certain that the medications prescribed to him will not be prohibited.
