These substances can get you sanctioned
Substances of note
Back in 2019 we published a blog post that would become one of the most-viewed on our website. It was a list of some of the more worrisome substances that are banned in sport and that had been responsible for athlete sanctions here in NZ.
We’ve updated and expanded that post for 2023 and beyond, adding more substances to avoid and the health consequences you risk if you use them.
Remember: If you play sport at any level, the Sports Anti-Doping Rules apply to you. If you’re found to use, possess, buy or traffic these (or any other) banned substances, then you could be subject to an anti-doping sanction, including a ban from all sport.
Before you take any substance, check if it's banned in sport.
