He has had no prohibited substance breaches since he began racing dogs in 2017. Despite the racing investigators being unable to trace the source of the drug, a charge was laid against Anderson before the Racing Integrity Board. Investigators said the level found in Hilton Hustler’s system was very low at just 0.7ng/mL of Methamphetamine and 3ng/mL of Amphetamine. For comparison, the international standard for positive drug test cut-off concentration applied in human drug testing is 300ng/mL. Because a source could not be found, the board opted not to penalise Anderson for the positive drug test.
