How fast can an emerald tree boa kill you?

It would be an impossibility for a Corallus caninus (Emerald Tree Boa) to actually kill a human being. However, their canines can get up to 3/4" long, so if you are bitten by one, you should seek medical assistance, as important arteries may have been cut. That would be the most severe thing that could happen. So, no worries!
