The World Anti-Doping Agency (WADA) has added xenon gas to its 2014 prohibited list for the substance's potential to enhance performance.
In a statement, WADA said its executive committee Sunday approved the modification of its 2014 prohibited list which will be effective following the required three-month notice period, reports Xinhua.
Scientific studies suggest that the gas artificially increases the levels of erythropoietin (EPO) in the blood, which is forbidden under WADA's rules.
