Kamila Valieva, a banned Russian figure skater, attributed her positive doping test to a strawberry dessert contaminated by her grandfather's heart medication. The Court of Arbitration for Sport (CAS) detailed in its report that Valieva, 15 at the time, claimed the banned substance trimetazidine entered her system through accidental contamination.
This explanation emerged after her positive test during the 2022 Winter Olympic Games, where she competed under the Russian Olympic Committee and initially won a gold medal. CAS, however, found her explanation implausible and insufficiently supported by evidence, resulting in a four-year ban effective until Christmas 2025, emphasizing strict accountability regardless of age.
