The war between Legion and Bilbo

[Douglas]

If you get bitten by a poisonous snake and get treated, then bitten say, a second time. Do you begin to build up a tolerance or immunity to the snake bite? Like if you handled snakes a lot and were bitten 30 or 40 plus times, could you begin to get immune to the bites?

I don't think getting snake bit would be the best way. But yes, they can inject themselves with small amounts of venom, as Legion already explained.
