haha! Yes but what? Cocaine? EPO? What was the purpose of the substance? Just trying to assess the seriousness. Agassi taking meth? Less serious that the stuff Canas was taking no?
He tested positive for nikethamide, a respiratory stimulant used to increase endurance at high altitudes that he apparently got from a glucose tablet. At least that's the excuse that was bought by the authorities. Actually, regarding Canas who tested positive for a diuretic, we don't actually know if he was taking anything else since diuretics are banned as they can mask PEDs because they increase the rate of urination to help athletes beat urine tests.
As many have noticed there has been a widespread increase in the amount of cramping in recent years, not only in tennis. The authorities need to really start doing far better testing as the likelihood is the cramping is a result of dehydration from diuretics. Let's face it, athletes know they have to drink a lot in hot weather and tough competition so they're hardly dehydrated simply from not taking in enough fluids. The more likely scenario is as a result of the electrolytes being depleted in their systems from diuretics which will allow them to take PEDs that the diuretics will then help to urinate out and thus beat the urine tests.
"Diuretics also involve a certain amount of risk – risk that goes beyond the possibility of detection.
The immediate consequence of diuretic use is fluid imbalance that can lead to dehydration. Other serious effects from high levels of diuretics can include heart arrhythmias,
muscle cramps, drops in blood pressure, and potassium deficiency.."
