The National Acupuncture Detoxification Association (NADA) teaches and promotes a standardized auricular acupuncture protocol, sometimes called “acudetox.” NADA claims acudetox

encourages community wellness . . . for behavioral health, including addictions, mental health, and disaster & emotional trauma.

I do not know what “community wellness” is or how one measures whether wellness has been successfully “encouraged.” In any event, in the NADA protocol, acupuncture needles are inserted bilaterally into the auricle (outer portion) of the ear at a depth of 1-3 mm at five specific points (sympathetic, shen men, lung, liver, and kidney) and left in place for 45 minutes.
