>>13282142it’s well known that you can build up an immunity to most toxins. it’s especially not surprising for snake venoms because many of those are neurotoxins and it’s similar to building up an immunity to many of the common illicit drugs on the market—for example the doses heroin addicts take regularly can far exceed a lethal dose of a non-addict
there is a funny story about a roman royal taking small daily doses of a bunch of poisons to immunize himself against them, since he was paranoid about getting poisoned by his younger brother who would inherit his claim to the crown. legend has it that a mob was out to kill him (painfully) and he tried in vain to commit suicide using large doses of poison but unfortunately he was totally immune and he got tortured to death nonetheless
