The Independent Anti-Doping Disciplinary Panel (IADP) ruled that the 17-year-old sprinter will be reprimanded with no period of ineligibility after her two-day anti-doping hearing earlier this week.
Williams had pleaded not guilty after testing positive for the banned substance hydrochlorothiazide (HCTZ) during the Jamaica National Championships in June.
The diuretic is prohibited by the World Anti-Doping Agency (WADA) for its ability to mask the use of performance-enhancing drugs.
The world U18 100m and 200m champion faced the IADP to determine whether she was at fault for it being found in her system.
In a statement released by the IADP, they concluded that “the athlete has established no significant fault or negligence as she was given tablets by her guardian and had no intention to cheat in her In-Competition sprint event on June 21, 2019.
“The IADP recommends that the athlete undergoes another education programme on Anti-Doping In Sports Rules as soon as JADCO carries out same.” - IADP
The Jamaica Athletics Administrative Association (JAAA) had provisionally named her to compete in the 100m and 4x100m relay at the ongoing World Championships in Doha, pending the outcome of the hearing.
