to paralyze/kill their prey and for protection...
Most snake venoms need to get directly into the bloodstream to work. Snakes keep their venom in an isolated sac. If they get any into their mouths, it is swallowed and digested to harmless substances, so the toxin doesn't get into the bloodstream. It is also thought that, to some extent, snakes have natural antivenom in their systems.

Not all snakes are poisonous. Some are constrictors which means that they bite their prey and wrap themselves around their food to suffocate the prey. Examples of constrictors are Ball Pythons and Anacondas. Poisonous snakes do have poison in their fangs though.
some types of snakes can eat the poison dart frogs, if they can cope with the poison.
The Cobra is a snake and can shoot poison as a projectile.
most snakes do drink through their mouths but desert snakes absorb it through their skin.
