Marc Farry has been cleared by the French Golf Federation after returning a positive drug test in June.
Farry tested positive during the French Open in June
The Frenchman had become the first European Tour golfer to return a positive drugs test.
But he was cleared after explaining that he was taking a medically prescribed drug used to treat a wrist injury.
In a statement Philippe Martin, president of the French Golf Federation, said Farry had been acquitted of any wrongdoing.
"The traces of steroids found in the urine of Mr Farry (on 29 June) at the time of the last round of the French Open, came as a result of an injection of cortisone with a therapeutic aim (tendonitis of the wrist) taken 21 days before," the statement read.
"There is therefore no intentional drug taking, the use of injectable cortisones (injections) being authorised by law if they are warranted for medical reasons."
Farry, who is preparing to play in the Linde German Masters at Gut Lärchenhof, said he was delighted by the verdict.
"(I am) relieved that this issue is now at an end once and for all," he said.
"I did not do anything wrong but nevertheless the last six weeks have been a really tough time for myself and my family.
"I am glad that this matter has been resolved and I can turn my attentions back fully once again to playing golf."
Farry was one of six players who undertook the voluntary test during the French Open.
The other five players - Philip Golding, David Howell, Peter O'Malley, Graeme McDowell and Francois Delamontagne - returned negative samples.
