Not only drugs, almost everything is bad at the wrong dosage. Case in point: water.

Tonicity matters too. Deionized water will suck the ions right out of you. All the way to your death if you're so determined.

Depending on your definition of poison of course, but at least for LSD and magic mushrooms, all that's known is a lower bound for their biological toxicity. For LSD IIRC it's somewhere in the 30mg (!) range, for mushrooms it's more than can comfortably fit a stomach. I'm afraid I don't have sources handy though.

That said, the state of mind must be so wild that "is it poisonous in this specific/usual sense" is probably not the right thing to discuss.

I've struggled to tell the difference between doses of LSD that exceed 100µg. Maybe I just take it too frequently to make much of a difference. It's also possible that it only increases duration, but not intensity.

So for mold, low enough doses aren't poison? Can't you just say this about anything. If you have poison in a low enough dose it's not poison. So it means jsut about nothing to say alcohol isn't poisonous because you can have a small dose of it.

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'.
