Did you even READ my original message? Go back and read it again. Then read it once more. And, for full effect, read it AGAIN.
As I pointed out from the very start, I can find no evidence to support the claim that NASA does drug tests on any animals (arachnids include) that the author of this piece claims. NASA does do experiments on weightlessness in creatures. But I challenge anyone here to find a NASA.GOV site that puts forth this information.
This third-party site should at least have some kind of footnotes on its claims, but no such data is provided. That tells me that someone's either misremembering, or they're pulling these factoids out of their butt.
