Yes, that’s quite true, and I have also mentioned several times now, that I don’t think anyone can assume human and anmal react the same way to any med (and additionally, that even humans don’t react the same to these drugs). And yes, I understand that just because I saw a patient be sick in 2 weeks after dosage, the drug can still be detectable in a horse; that wasn’t my point, my point was that it isn’t all that set what these drugs do to any given individual.
There is some enzyme, p340? Something like that? I can’t remember, that causes humans to eliminate drugs very fast. If people vary in drug clearing times, horses may too. If the vet’s only experience was in animals with faster clearing times(if it exists), perhaps his advice on clearing times is based on experience, not research (not a ton of research on a drug that is illegal and isn’t supposed to be used in competition).
But if we know all that, and it’s so easy to find out, the knowledge is so ubiquitous that a bunch of ammy riders in USA are as familiar with it as people here are, even having used it, and if in fact all this is such common knowledge, why wouldn’t Isabel know it. She certainly is more in that world and would know a lot about what people are giving horses - horse people talk to each other about these things and vets talk to horse people etc.
If it’s so stupid to show in two weeks and so easy to know not to, why would Isabel think otherwise?
