I'd say that's a fair addition. However, we also have confirmed that this toxin in dispersed throughout the body, where it remains inturned. Whereas I assume most measurements of toxicity assume a transient status and eventual expulsion from the body. But that's a guess on my part. Regardless, lethal toxicity is not the same as toxicity in general. For example, how dangerous is NGO within marrow? Where does this leave us? I expect well within the unknown.
