I think it's interesting how many colubrids actually have venom and fangs. Take the redbelly snake for example. I was in the lab watching one eat a slug. It had it about half way down when I opened to cage to take a picture. The snake let go but I observed the slug and it appeared to get weaker and weaker. This could be an effect that comes from being half swallowed but it was interesting.

I think most venom in colubrids are intended to weaken or kill the prey item wether it be insect, slug, amphibian, or whatever and it would be interesting to see if those venoms had any effect on mammals (lab rats-not my hand of course).
