If you mean what Justin Bieber tested positive for, there are two major incidents that are often confused:
- COVID-19 (2022): In February 2022, Bieber tested positive for COVID-19. His representatives confirmed the diagnosis after he had begun his Justice World Tour. Several shows were postponed as a result.
- THC and Xanax (2014): After Bieber’s January 2014 arrest in Miami Beach for DUI-related allegations, a toxicology report found THC, the main psychoactive component of cannabis, and alprazolam (Xanax) in his system. This was a toxicology result, not a disease test.
There is also an important separate health disclosure: in 2020, Bieber publicly revealed that he had been diagnosed with Lyme disease and infectious mononucleosis.
If you’re referring to a recent claim that Bieber “admitted he tested positive” for something specific, tell me where you saw it (TikTok, YouTube, news article, etc.), and I can identify exactly what claim it refers to.
