re: 40 year old "wellness coach" dies after injecting poisonous frog venom

You can buy and keep poisonous dart frogs, and be 100% safe while doing it. They derive their poison from their diet by sequestering chemicals contained in the insects they eat. Those chemical are stored in really high levels and transported to their skin.

Take the frog out of its native environment — away from it's natural prey — and it is no longer poisonous. You could really mess with some people if you wanted.
