My three year old is stoned out of his head on this stuff. It has not effected his cough at all, but he now falls asleep or "passes out" without notice. His eyes are dialated, he is "spacey" and is having nightmares and when awake, what I think are hallucinations. He has trouble with motor skills- even the simple things. We have stopped using it now and after 24 hours he is started to become a little normal. VERY unsettling.
