The key idea is that toxins are incredibly potent, so the main practical hurdle in using them as weapons is the need for extremely precise dosing. Because a tiny amount can cause severe harm or death, there is a very narrow margin between an effective dose and a dangerous one for the attacker, the target, and bystanders. This makes reliable weaponization—getting enough toxin to produce a desired effect without causing unintended self-harm or excessive collateral damage—extremely difficult. In real-world conditions, factors like delivery method, route of exposure, formulation, and environmental degradation all influence the actual dose received, leading to unpredictable outcomes. That fragility of effect opposed to the huge lethality of tiny quantities is what limits the usefulness of toxins as weapons.

Detectability, stability in the environment, and production cost are important considerations, but they do not undermine the fact that the same extreme potency that makes toxins dangerous also makes precise, controlled use exceptionally challenging. The need for meticulous dosing at minute scales stands out as the primary limitation in weaponizing toxins.
