CANA is a United States military acronym for "Convulsive Antidote, Nerve Agent", the drug diazepam in injectable form.

One CANA kit is typically issued to U.S. service members along with three Mark I NAAK kits when operating in circumstances where chemical weapons in the form of nerve agents are considered a potential hazard. (Both of these kits deliver drugs using auto-injectors. They are intended for use in "buddy aid" or "self aid" administration of the drugs in the field prior to decontamination and delivery of the patient to definitive medical care.)
