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.
 * Snakes summoned by Orochimaru and others, sometimes are able to secrete venom from their fangs.
 * Tsunade has been noted by Jiraiya to be the only person capable of poisoning a ninja without their knowing, as she managed to spike his sake with an odorless, colourless poison that left him unable to properly control his chakra.
 * Kabuto Yakushi has developed a poison which is specifically designed to suppress the Wood Release kekkei genkai.
 * Aniki, the leader of the Moya Triad, had tried several types of poison against Kakashi, which were to make him hiccup, laugh, and cry uncontrollably until he died from it.
 * The Three Wandering Ninja used the Five Senses Confusion Disorder, an odorless type of poison powder that slows down the victims' senses and reaction time.
 * Fuen used a poison that is thin and tiny enough to be taken into the air, and cause those who inhale it to see whatever she wants.
 * Sasori has developed a poison that even if a small amount is introduced into the bloodstream, the affected person will die within three days while also being painfully paralysed for the duration. The antidote for this poison is extremely complex - so much so that no one in Sunagakure was capable of creating it.
 * One of the poisons taught to Sakura by Shizune is abe to be entrenched on kunai and has a delayed effect, as Naruto was cut with it but collapsed some time afterward.
 * Sakura also uses bombs that contain a strong knockout gas that can render even strong ninja like Sai, Lee, and Kiba unconscious in moments.

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 ninja bees that can inject venom into a enemy through their stingers.
 * Nano-sized, venomous 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 kunai so that if she is able to cut the target, 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 in his Iron Sand, which is far less noticeable.

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, with her Poison Mist technique. Inhaling the slightest bit of poison can prove fatal, as seen when Sasori trapped Sakura in two consecutive waves of his poison mist.

Combating Poisons
Certain characters have encountered poisons throughout their careers as ninja. Those skilled in the fields of chemistry and biology are capable of producing antidotes to the poisons. Tsunade, during the Second Shinobi World War, was able to produce antidotes to every one of Elder Chiyo's poisons, much to the latter's resentment. During the mission to rescue Gaara, 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 most poisons, such as the one that Shizune taught to Sakura Haruno in order to use on her kunai.
