Can the more educated amongst you in the preclinical sciences tell my when you inhale a noxious substance nasally the ipsilateral eye can water?
Incase you are wondering, no I have not just snorted a line of coke.

Presumably because the inhaled noxious substance goes up the ipsilateral lacrimal duct and irritates the eye?

Irritation of the nasal mucosa can trigger the lacrimation reflex (V afferent, VII efferent) - it's not just if you stick stuff in your eye. Can't remember if it is ipsilateral or bilateral. Alternatively, maybe some of this mysterious chemical got directly into your eye too?
