Applying Poison

One dose of poison smeared on a weapon or some other object affects just a single target. A poisoned weapon or object retains its poison until the weapon scores a hit or the object is touched (unless the poison is wiped off before a target comes in contact with it).

Applying poison to a weapon or single piece of ammunition is an action. Whenever you apply or ready a poison for use, there is a 5% chance that you expose yourself to the poison and are attacked by the poison as normal. This does not consume the dose of poison. Whenever you attack with a poisoned weapon, if the attack roll results in a natural 1, you expose yourself to the poison. This poison is consumed when the weapon strikes a creature or is touched by the wielder. If you are proficient with poisoner’s kits, then you do not risk accidentally poisoning yourself when applying poison.
