It has been revealed that 13 footballers have tested positive for drugs since 2012, with the Football Association refusing to publicise their names.
The FA believe that players who have been caught with recreational drugs, like cocaine and ecstasy, in their system should be protected to aid their rehabilitation process.
Last week, the Daily Mail revealed that Saido Berahino was banned for eight weeks after testing positive for a social drug in September while at West Brom, although his lengthy absence, at the time, was put down to fitness issues rather than the suspension.
Football currently conducts the most drugs tests in any sport, with 2,442 samples taken last year and 3,000 expected to be undertook this campaign.
There were three positive tests last season, six in 2014/15, three in 2013/14 and one in 2012/13.
Of the 13 incidents, former Sheffield United and Everton man Jose Baxter is believed to account for two, while Aaron McCarey, formerly of Wolves, is also thought to be one after the Midlands club named him.
The FA’s testing programme is more thorough than what cycling, tennis and athletics currently have in place.
Both the players and their clubs must submit their whereabouts so the FA can perform random drug tests on any giving day, either at training grounds or home addresses.
The footballing body’s aims of practice are: “To uphold and preserve the ethics of sport. To safeguard the physical health and mental integrity of players. To ensure that all players have an equal chance.
“The FA’s Anti-Doping Regulations are WADA Code compliant and The FA works closely with its stakeholders to ensure that the anti-doping programme is effective and maintains the integrity of English football against the threat presented by doping in sport.”
