Blowgun

The blowgun is a popular weapon among ninja because it is inexpensive, simple to use, and can be used outside of combat as a breathing implement while submerged (which comes up more often than one might imagine for ninja). Small dans are placed within the tube and then propelled at the target by blowing through it forcefully. Although the darts inflict virtually no damage, they are usually poisoned, which is the real benefit to using this weapon in the first place. Blowguns have an effective range of fifty feet.
