Honestly I'd probably get the sensation of being sick before I ever became high from chocolate. Just pass me the green leaves...I did have an experience once though when I was walking the halls of my school eating a Reeses and all of a sudden I felt like I usually feel when I'm starting to feel the high from weed. But it wasn't intense at all..didn't even compare to a strong buzz but it was weird since it happened right after I ate the thing lol.
