Doping Controversies
In 2003, Puerta received a two-year doping suspension after testing positive for clenbuterol at Viña del Mar. In his defence, he argued that the substance had been administered to him by his doctor to combat asthma and that it had no performance-enhancing effect. The sanction was subsequently reduced to nine months suspension, effective from October 2003, and a $5600 fine.
In December 2005, Puerta was once again banned, this time after it was revealed that he had tested positive for the use of the cardiac stimulant, etilefrine, following his 2005 French Open final loss to Rafael Nadal. The suspension was for 8 years, the longest in tennis history at that time. As a result, Puerta was forced to forfeit all his rankings points and prize money (€443,282/£300,671/$456,000) from the 2005 French Open onwards, and had all his 2005 results from after the French Open, annulled. Puerta's runner-up finish at the 2005 French Open was allowed to remain on the record books.
The International Tennis Federation tribunal noted, however, that "The amount of etilefrine detected in the positive drugs test was too small to have any effect on his performance". Puerta appealed against the ban, claiming on his web site that he only ingested trace amounts of it accidentally left over by his wife in a glass. On July 12, 2006 his suspension was reduced to 2 years by the Court of Arbitration for Sport, making him eligible to restart his career on June 5, 2007.
