CBJJ is the 2nd largest federation for Brazilian jiu jitsu. They’ve now opted to incorporated testing in their process in some way:
It’s unclear under which body the testing will be done. IBJJF is typically covered by USADA a part of World Anti Doping Agency (*WADA).
Testing has long been a controversial subject due to high cost and globally spread suspicion that doping is something majority of high level competitors use to enhance their performance.
While testing is a good idea in theory, it comes at a huge price. So it’s likely if the athletes still have to pay registration and membership fees outside of the cost of the test, they just won’t do it depending on how it’s structured.
