If you were to refine cannabis down to pure THC, I'm sure it'd have a toxicity level as well. Cannabis, like iceberg lettuce, doesn't have a toxicity level because of chemicals contained in it. And cannabis, like iceberg lettuce, could have stuff extracted out of it which would be toxic in large amounts at high concentrations.
