I can’t understand how a small grain, a speck of toxin can kill a grown adult?

Well, it does depend on what kind of poison it is, but for example a poison could send a specific signal to stop your heart. It just needs to “press on the button” and it’s done. It won’t do it itself.

Nerotoxins “eat” brain cells. So obviously, even a little bit can do a lot of damage. And nothing is gonna stop it.

There’s also strongly radioactive components that will just make your cells degenerate. They hold a lot of energy, so that’s why.

There is a bunch of other ways to kill people, I’ll let you read the other comments 🙂
