We often focus on athletes who've been caught with performance-enhancing drugs, but some sports stars have tested positive for recreational drugs. Diego Maradona was banned from football for 15 months after testing positive for cocaine in 1991. Later that year, the soccer icon was given a 14-month suspended sentence after being caught in possession of half a kilo of cocaine. American sprinter Sha'Carri Richardson tested positive for THC at the 2021 US Olympic trials, which saw her receive a one-month ban and miss the Olympic Games. Tennis player Nick Kyrgios was suspended from tennis by the International Tennis Integrity Agency after testing positive for cocaine in June 2026. Two-time NBA Champion J.R. Smith tested positive for marijuana in 2013, which saw him receive a five-game ban; however, NBA players no longer get suspensions for marijuana use. UFC Star Nick Diaz received multiple suspensions by the Nevada Athletic Commission for testing positive for marijuana metabolites following fights.
