USADA have just announced that Tayane Porfirio has been suspended from IBJJF competition for a period of three months after she returned a positive test. Porfirio tested positive for Carboxy-THC, a urinary metabolite of tetrahydrocannabinol (THC) during a routine test at the IBJJF World Championship 2026 on May 31st, 2026. This is the main psychoactive constituent of cannabis, marijuana, and hashish; she tested above the urinary Decision Limit as the result of that sample collected earlier this year. Porfirio’s suspension starts from the date she was first provisionally suspended, July 8th, 2026 and will run up to October 8th, 2026; so she has already served the majority of it.
Additionally, Porfirio has been stripped of any titles or medals that she has won since the date of her positive test; including her pair of IBJJF World Championship silver medals. The IBJJF has yet to update their standings from that event but their standard practice is to promote the bronze medalist that Porfirio beat to silver, and then announce a new bronze medalist in their place. This is also the second time that Porfirio has been suspended and stripped of medals at the world championship, as she tested positive for nandrolone in 2018 as the result of an in-competition test at the world championship that year.
She received a four year suspension back then and athletes would normally receive harsher penalties for a second offence within 10 years, but USADA have declined to apply that rule due to the circumstances surrounding the test. They advised that “she is not subject to an increased sanction in this case under the applicable rules because her use of THC occurred out-of-competition and was unrelated to sport performance.” She is also eligible to have her sanction reduced to just one month if she satisfactorily completes a treatment program approved by USADA, but she only has a little over a month remaining of her suspension and there are no major gi IBJJF events coming up in that time.
Tayane Porfirio later shared her statement on the positive test and subsequent USADA suspension in a post to her official Instagram account:
