Olympic gold medallist Marlon Devonish insists he would have no issue being on the same relay team as Dwain Chambers at this summer's London Games.
Devonish also believes Britain's 4x100m relay team will be stronger if Chambers is in the line-up.
Chambers is likely to discover next week if his lifetime Olympic ban from the British Olympic Association has been lifted by the Court of Arbitration for Sport, which will determine if he will be able to compete at London 2012.
Devonish, who helped Britain win relay gold at the 2004 Olympics in Athens, told the Daily Mail: "I've got no problem passing the baton to him or receiving if from him.
"People make mistakes.
"Dwain should make the relay team stronger because he's been the fastest sprinter in Britain in the last few years.
"It is about us doing well and the relay is our best chance."
Regarding bans for drugs cheats, Devonish added: "I think the whole world should have the same system and that the ban should be longer - four years would be about right.
"Four years means you miss an Olympics and that is more of a deterrent."
Chambers tested positive for the banned substance THG in 2003 and despite several appeals his two-year ban stood, with the BOA issuing a lifetime ban from competing for Great Britain at future Olympics, and a number of previous results were also nullified.
He made a return to the track after several other sporting ventures, including a brief foray into rugby league, failed and won gold in the 60m at the 2010 World Indoor Championships.
