We appreciate that in Mrs [Campbell-Brown]'s case, JADCO operated merely as an agent for the International Association of Athletics Federation (IAAF), under whose auspices she performed last year when she returned a positive drug test. It is also noted that JADCO was not the agency responsible for the adjudication of Mrs Campbell-Brown's case.
Professor [Wayne McLaughlin], a biochemist, responded saying that while the stimulant was of a higher concentration in the athlete s sample - 720 nanograms per millilitre - it would be difficult to say since the effects of the stimulant on an athlete vary depending on the individual. He did acknowledge, however, that the stimulant could have had a direct effect on the athlete s neurotransmitters, which could mean that the athlete may have been aware of the effects on his body.
