Life bans from sport is the aftermath for athletes found guilty of doping offences and the use of performance-enhancing drugs. Recently, retired world champion racing driver Mario Andretti has called for life ban for Franck Montagny after the latter tested positive for a cocaine derivative.

In an article by Germany's Welt newspaper, Andretti said that Montagny should be banned for life if he had his way. According to the 75-year-old Italian American, Montagny is a big disappointment in the sport, who risked not only his career, but also the careers of other drivers on the track. "What he has done is unforgivable to the sport," Andretti was quoted saying.

Nonetheless, Andretti believes that the use of banned performance-enhancing drugs is not widely practiced in motorsport. He reckons that that anti-doping committees are doing what they are supposed to do.

"There are some black sheep, but it doesn't mean that there is doping or drug problem in racing. Montagny is now busted, so it shows that the control system works."

Montagny admitted to French news outlet L'Equipe the real reason why he wasn't in attendance at the Formula E event in Uruguay in December 2014. He revealed that he tested positive for a cocaine derivative in a test that was carried out after the second Formula E round at the Putrajaya ePrix in Malaysia on Nov. 22.

Montagny did not contest the result of the test. He was immediately suspended to take part in any racing event. Fédération Internationale de l'Automobile, or FIA, has yet to announce Montagny's official sanctions.

In May 2014, it was announced that Montagny will race for Andretti Autosport, which is headed by Andretti's son Michael. He was chosen to represent the team in the inaugural season of 2014-2015 FIA Formula E Championship. He raced in Beijing, where he finished second. Montagny also took part in the ePrix event in Malaysia, finishing 15th, but pulled out of Formula E round three event at the the Punta del Este in Uruguay. In the fourth round at the Buenos Aires ePrix, Montagny was replaced by IndyCar driver Marco Andretti.
