KINGSTON, Jamaica (AP) — Jamaican 400-meter runner Dominique Blake has been banned from the track for six years after failing a dope test.

Blake tested positive last year for methyhexaneamine, a stimulant that is commonly used as a nasal decongestant and is banned in competition. It was Blake's second positive test. The 26-year-old sprinter was banned for nine months after ephedrine was found in her system in 2006.

On Thursday, the Jamaica Anti-Doping Disciplinary Panel handed down the ban for Blake's positive test in June during Jamaica's Olympic trials. She had placed sixth in the 400-meter race.

Blake's spokeswoman did not immediately respond to an email seeking comment.

Blake ran for Penn State University in the U.S. from 2004 to 2008.
