Commonwealth Games gold medallist Chris Rae has been banned for two years after a second doping offense for cannabis.
Rae, the super heavyweight weightlifting champion at the 2006 Melbourne Commonwealth Games, returned a positive test at the Australian titles last August.
The 27-year-old Rae had previously served a six-month suspension for cannabis use in 2004.
The Australian Weightlifting Federation said the two-year ban was mandatory for a second offense.
The competition ban extends to August 2009.
