[11] A major investigation by the Guardia Civil into doping in Spain, known as Operación Galgo, began in April 2010 and made headline news in December following a number of arrests.

[12][13] Marta Domínguez, world steeplechase champion and vice president of the Spanish Athletics Federation, was implicated in the blood doping ring.

[15] Olympic champion Shelly-Ann Fraser received a six-month ban after a positive test for pain relief narcotic oxycodone at the Shanghai Diamond League meeting.

Her coach Stephen Francis, who had the painkiller on prescription for his kidney stones, gave the banned substance to his athlete to relieve her toothache.

The substance can be used as a complement to steroid cycles, but can also act as a fertility drug and Jones-Ferrette (who announced her pregnancy in November) claimed this was the intended usage.

[21] Retired American sprinters Ramon Clay and Crystal Cox received retrospective bans from the United States Anti-Doping Agency due to their steroid usage relating to the BALCO scandal period from 2001 to 2004.
