Abstract
Abstract A poison dart for subduing a person having poison with effects that occur long enough after a person is struck by the dart to allow for treatment that prevents those effects. This makes a person struck by the dart likely to stop committing undesireable behavior and instead seek treatment. The dart has a readily identifiable substance, dispersible in the human body, to aid in identifying the poison and a substance, dispersible and relatively persistant in the human body, for indicating that a person has been struck by the dart within the past month. It is separable into a front part that carries the poison and becomes buried into flesh upon impact and a rear part which projects from the flesh and can be pulled free from the front part if it is pulled on. This helps ensure that the front part will remain in the flesh long enough for the poison to dissolve away from it. The dart does not cause rapid disablement and therefore is not useful for committing a crime like armed robbery.
