Rugby league player receives sanction

8 January 2020

The Australian Sports Anti-Doping Authority (ASADA) today acknowledged the decision of the NSW Rugby League Anti-Doping Tribunal to impose a two-year ban on athlete Thomas Carr for the presence of prohibited substances and use of a prohibited substance.

Mr Carr, who played for the Canterbury Bankstown Bulldogs in the Intrust Super Premiership, returned an Adverse Analytical Finding (AAF) from an in-competition doping control test on 28 July 2018 which detected the presence of 1,4-Dimethylpentylamine and Higenamine.

It was determined that on and/or before 28 July 2018, Mr Carr used the prohibited substance Higenamine.

Mr Carr is ineligible to participate in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 8 September 2020.

Additional information on the prohibited substance

1,4-Dimethylpentylamine is only banned in-competition under the S6 classification of Stimulants. The substance is similar in structure to 1,3-dimethylamylamine (DMAA), which can cause side effects including cerebral haemorrhage and heart attacks and has been linked to a number of deaths in Australia and overseas.

Higenamine is a S3 class Beta-2 Agonist (these type of substances allow lungs to take in more oxygen) and is prohibited in and out-of-competition. However, as a cardiotonic, Higenamine can increase heart rate, putting an athlete at an increased risk of arrhythmias and even death.

ASADA is committed to protecting the right of clean athletes to fair competition. If you are aware of any suspicious doping activity, you can report it anonymously via the ASADA website: www.asada.gov.au/report-doping or call us on 13 000 27232 (13 000 ASADA).

ASADA recommends you check all your substances before you take them on the ASADA Clean Sport app. For more information visit: ASADA tech.
