I know everyone likes to say that the rule has something to do with “intent.” It actually doesn’t.
The relevant portion of GR 410 states:
- No horse and/or pony competing in a Breed or Discipline designated as (or part of) a Therapeutic Substance Group is to be shown in any class at a competition licensed by the Federation (see also GR402.1, last sentence) if it has been administered in any manner or otherwise contains in its tissues, body fluids or excreta a forbidden substance except as provided in GR411. Any horse and/or pony that competes in more than one Breed, Discipline, and/or Group at a competition,one of which is a No Banned Substance Group, shall be required to be in compliance with the No Banned Substance Provisions at all times while competing in any and/or all classes and/or divisions at that competition. [B]For purposes of this rule, a forbidden substance is:
[/B]a. Any stimulant, depressant, tranquilizer, local anesthetic, psychotropic (mood and/or behavior altering) substance, or drug which might affect the performance of a horse and/or pony (stimulants and/or depressants are defined as substances which stimulate or depress the cardiovascular, respiratory or central nervous systems), or any metabolite and/or analogue of any such substance or drug, except as expressly permitted by this rule.
It has NOTHING to do with whether or not you INTEND for something to affect performance. In order to be a “forbidden substance,” something must be: (a) a stimulant, depressant, tranquilizer, local anesthetic, psychotropic substance, or drug AND (b) something that might affect the performance of the horse. You must have A and B for something to be a forbidden substance.
SO - Magnesium is NOT a forbidden substance because it is NOT a stimulant, depressant, tranquilizer, local anesthetic, psychotropic subtance, or drug. It is a MINERAL. And a mineral that occurs naturally in the horse’s body at that. Same with B vitamins. Same with Red Cell. Same with electrolytes. Same with most supplements. While each of these things might affect the performance of a horse, particularly a horse with deficiencies, they are NOT forbidden substances because they do not meet the first criterion (they are not “stimulants, depressants…etc.”)
FURTHER, if something IS a stimulant, depressant, drug, etc. (thereby meeting the first criterion), it must ALSO be something that “might affect the performance of the horse” in order to be a forbidden substance. It has nothing to do with what you intend. It simply has to be something that “might affect the performance of the horse.” This is an objective standard, although a very poorly defined objective standard due to the use of the word “might” which is far too open to interpretation. (A better, more effective and easiliy applied standard would be “reasonably likely to affect.”) You can have all kinds of good “intent” that 3 ccs of Ace won’t affect the performance of your horse, but the fact is that, objectively, it “might” (of course, it WILL).
Likewise, you can have all kinds of intent that some substance that can be accurately characterized as a “depressant” will have a sedating effect on your horse, but the fact of the matter is that if for some reason that substance has no chance of having a sedating effect on horses (perhaps it is known that it does not have a sedating effect on horses because of the way they metabolize it…I don’t know…just making this substance up for the point of argument), then it is NOT a forbidden substance under the rule because there is no chance that it “might affect the performance of the horse,” notwithstanding the fact that it can be accurately classified as a “depressant.”
I repeat, THE RULE AS DRAFTED HAS NOTHING TO DO WITH INTENT. It is all purportedly “objective.” There is no use of the word “intent,” and you can’t even imply it into the rule. Like most USEF rules, this one is poorly drafted, confusing, and difficult to enforce.
USEF needs to figure out what it wants to ban and then DRAFT RULES THAT MEAN SOMETHING. For what it’s worth, I would LOVE to see a rule that bans the use of IV magnesium. That would not be difficult to draft, and it would go a lot further toward protecting horses than a lot of spatting over whether or not someone is giving feed-through magnesium in a supplement. Heck, if USEF wants to ban supplements or vitamins of any kind, FINE. I won’t be showing because it wouldn’t be in the best interest of my horse, but at least that would be a clear rule.
