The difference between difference between types of snakes

[Trackstrong83]

Yes, there are many rear-fanged venomous snakes that are colubrids.

Oh yes forgot about these, but almost all of these snakes are non lethal to humans correct? Like hognoses and vine snakes, both are rear fanged and TECHNICALLY venomous, but if you were bitten there may be some irritation, but non lethal to humans correct? I'm not 100% sure.
