Coleman -- who is legally deaf -- was arrested for vehicular assault and hit and run in Bellevue, Washington after allegedly leaving the scene of a crash in which the other driver sustained serious injuries.
Now, cops have released the 102 page report on the investigation -- in which officials say Coleman admitted smoking spice ... and also had a lighter, a glass spoon pipe with residue and an opened bag of synthetic weed labelled "F'd Up!" and 3 unopened bags of a strain called "Mad Pitbulls."
But get this ... despite the admission, cops say Coleman's blood tested NEGATIVE for marijuana.
