To achieve a pharmacolgic effect

[C Eyler <eyler@mindspring.com>]

The list of impermissable substances posted on endurance.net includes:
"nutrient substances administered in doses to achive a pharmacologic effect
(DMSO, DMG, yucca and MSM)"

So, if a rider is supplementing biotin, and the biotin mix includes some
yucca, does that constitute a 'nutrient (yucca) administered in doses to
achieve a pharmocoligic effect?'

We seem to have a disconnect here between "to achieve a pharmacologic
effect" and the trace evidence that can be detected in current drug
testing.  I realize that it is not possible to predict how long a substance
will remain in the body of a particular horse, but could we not define the
levels that constitute a "a pharmacologic effect?"

Again, the intent here is not to try to get away with anything or to
compete a horse that is still recovering from an illness or injury.  Just
don't want to end up in violation of drugs restrictions because my horse
was sedated to have his teeth floated or because I used the wrong biotin
supplement.
