Fentanyl is actually much more toxic than the mycotoxins produced by mold (which I'm guessing is what you're referring to), and yet fentanyl is generally recognized to be a useful drug because of its therapeutic effects. If something has no possible therapeutic, recreational, nutritional, or culinary effect, while being toxic, it might be fair to characterize it as a 'pure poison'.
That's a good definition. Still, you can take it literally - anything small enough doesn't really harm you. and meanings can be stretched to support whatever conclusions you want.

What about prions, or strange matter?
You think you can't make those any smaller?
I would assume you can't generally just shrink the size of basic particles, molecular bonds or fundamental forces, but maybe you can, who knows.
