Olivia TaylorNBA star Paul George served a 25-game suspension in the 2025-26 season after violating the NBA's anti-drug policy by taking what the league described as "improper medication." He has since returned — and entered the 2026 playoffs with the Philadelphia 76ers fully healthy, his first healthy postseason since joining the team. The episode has renewed a critical conversation for Australian athletes at every level: can a supplement or prescribed medication get you suspended, banned, or disqualified without you ever intending to cheat?
What Happened with Paul George
George was suspended from 25 NBA games under the league's anti-drug policy for "improper medication." The NBA did not publicly classify the substance as a performance-enhancing drug, and no suggestion of intentional doping was made. The violation appeared to relate to a medication that was not properly disclosed or cleared under the league's programme — a category of violation that catches athletes off guard more often than most people realise.
Compounding the situation, George was also managing his recovery from an arthroscopic left knee procedure performed in July 2025. He missed a significant portion of the 2025-26 season before making his debut against his former team, the Los Angeles Clippers. Following his return from suspension in March 2026, George showed improved form — and by mid-April 2026, the Philadelphia Inquirer reported that he had entered the postseason healthy for the first time since joining the 76ers. Game 5 of the Celtics-76ers series saw him contribute alongside Joel Embiid (33 points) in a 113-97 Philadelphia win that kept the series alive at 3-2.
For millions of Australian recreational athletes, weekend warriors, and sports club participants, George's case is a warning shot. Supplements and medications that are freely available at a pharmacy or health food store in Australia may contain substances prohibited under anti-doping codes.
How Anti-Doping Rules Affect Australian Athletes
Australia's national anti-doping framework is administered by Sport Integrity Australia, operating under the National Anti-Doping Policy which aligns with the World Anti-Doping Agency (WADA) Prohibited List. The key principle that catches athletes unaware is this: strict liability.
Under strict liability rules, an athlete is responsible for any prohibited substance found in their body — regardless of how it got there, and regardless of intent. "I didn't know it was in my supplement" is not a defence to a doping violation. It may reduce the length of a sanction if an athlete can demonstrate no fault or negligence, but it does not eliminate the violation itself.
According to Sport Integrity Australia, the most common source of inadvertent doping violations in Australia is contaminated or mislabelled supplements — products that are sold legally but contain substances that appear on the WADA Prohibited List, sometimes without disclosure on the label.
The Supplement Problem in Australia
The Australian supplement market is large and largely unregulated at the point of ingredient disclosure. The Therapeutic Goods Administration (TGA) oversees medicines and some supplement categories, but many sports supplements — protein powders, pre-workouts, fat burners, and testosterone boosters — are sold as food products rather than as therapeutic goods, meaning they face lower labelling and quality standards.
Research conducted with Australian elite athletes and sports scientists has identified multiple categories of supplements that present elevated risk of inadvertent doping:
Pre-workout formulations. Many pre-workout products contain stimulants that are either on the WADA list or closely related to substances that are. This category has the highest rate of contamination findings across tested samples globally.
Weight management products. Some products marketed for fat burning or weight loss contain diuretics, stimulants, or hormonal precursors that are prohibited in competition. These products are sometimes imported from overseas and do not meet the labelling standards applicable to Australian-manufactured products.
Testosterone and hormone support products. Products sold as "natural" testosterone support or male hormone enhancement frequently contain compounds that are derivatives of or functionally similar to prohibited anabolic agents. Athletes — including those in recreational club competitions — can test positive even from products that do not declare prohibited ingredients.
Herbal and traditional medicine products. Some traditional herbal preparations used for energy, recovery, or general wellness contain naturally occurring compounds — including ephedra derivatives and certain plant extracts — that appear on the WADA Prohibited List.
What Australian Athletes Should Do
If you compete in any organised sport in Australia — including club-level competition in AFL, rugby, swimming, cycling, athletics, or any code with WADA-aligned drug testing — the following steps significantly reduce your risk of an inadvertent doping violation:
Check before you take. Use the Sport Integrity Australia drug checking service or the Global DRO (Drug Reference Online) tool to verify any supplement or medication before use. This applies to prescribed medications as well as supplements — some therapeutic medicines contain banned substances and require a Therapeutic Use Exemption (TUE) before use in competition.
Disclose all medications and supplements to your doctor. Before any new prescription, inform your treating doctor that you compete in sport and may be subject to drug testing. Not all GPs are familiar with WADA rules, so being proactive is important.
Choose supplements with third-party testing certification. Supplements that carry certification from Informed Sport, Banned Substances Control Group (BSCG), or NSF Certified for Sport have been independently tested for over 270 banned substances. These are not foolproof but represent significantly lower risk than uncertified products.
Be especially cautious with online and imported products. Overseas-sourced supplements — purchased via social media or international online platforms — carry the highest risk of unlisted prohibited substances and contamination.
When to Consult a Health or Legal Professional
If you have received notice of a potential doping violation, or if you are uncertain about the status of a medication or supplement, professional advice is available. A sports medicine doctor can assess your situation, assist with Therapeutic Use Exemption applications, and liaise with Sport Integrity Australia on your behalf.
For athletes who have already received a notice of charge, a lawyer with experience in sports law and anti-doping proceedings can help you understand your rights, present mitigating evidence, and navigate the dispute resolution process under the relevant national sporting organisation's policies.
