Poison

Poisons, toxins and venoms are all poisonous, intoxicating substances - powders, liquids and gases - that can be used by ninja in combat. Poisons come with a variety of effects from body weakness, paralysis or death.

Types
There are different types of poison, some more effective than others. For example, Sasori has developed a poison that even if a small amount is put in the body the will be subject to death within three days. Tsunade has also been noted by Jiraiya to be the only person capable of poisoning a ninja without their knowing.

Insects
There are several species of insects that use poison in their attacks. While other insects, such as the Kikaichū, can be cultivated for the purpose of neutralizing poisons and toxins used on the bug-user's allies.


 * Bees - The Kamizuru clan of Iwagakure has Ninhachi can inject poison into a enemy through their stingers.
 * Moths - Fuen first uses poison that is thin and tiny enough to be taken in the air. Her target will inhale the poison and start to see the things that Fuen chooses, like caves, moths, or allies of the target trying to kill the target. The moths in this technique in fact scatter poison.
 * Nano-Sized, Poisonous Insects - Torune and Shikuro Aburame can subsequently infect the opponent with these bugs, causing an excruciatingly painful and likely fatal injury, unless the afflicted area is swiftly removed. However, there is in fact an antidote, but only Shikuro Aburame knows how to make such an antidote.

Usage
Most poison users use poison through weapons. For example, Sakura puts poison on her kunais so that if she is able to cut the target with the kunai, they are instantly injected with her poison. Puppet-users, such as Chiyo, Kankurō and Sasori, prefer to put poison inside their puppets so that they can activate it when they are in need. Sasori, similarly to Sakura, puts poison that is clearly noticeable on the blades of his puppet, the Third Kazekage, as well as his Iron Sand.

Poison may be used in other forms, not only as a liquid substance. It can be used in a mist form, as demonstrated by Shizune, when she used her Poison Mist technique. Inhaling the slightest bit of poison mist can prove fatal, as seen when Sasori trapped Sakura in his poison mist.

Combating Poisons
Certain characters have encountered poisons throughout their careers as ninja. Those skilled in chemistry and biology are capable of producing antidotes to the poisons. Tsunade, during the Second Great Shinobi World War, was able to produce antidotes to every one of Elder Chiyo's poisons, much to the latter's resentment. During the 'Kazekage Rescue Arc', Sakura Haruno demonstrated the skill to not only extract and analyze Sasori's poison swiftly, but also produced an antidote to counter it.

Apart from using antidotes to poisons, a ninja can also work to build-up a tolerance to certain poisons by gradually exposing oneself to non-lethal amounts of those poisons. Orochimaru, in the effort to make Sasuke Uchiha into the perfect vessel for his Living Corpse Reincarnation technique, made it a point to make Sasuke immune to poisons, such as the basic ones that Shizune taught to Sakura Haruno in order to use on her kunai.
