“”Have you ever SEEN someone high on opiates and/or marijuana. Ramming oneself into a van door is not what one would expect from opiates/marijuana. “”
As a matter of fact, I have seen this very thing. A person high on a cocktail of drugs raging and fighting with anyone and everyone in reach, and fighting restraints to the point if permanently injuring themselves.
The ONLY person trying to hurt Mr Gray was Mr Gray himself.
What drugs? Different drugs (obviously) have different effects on behavior. Opiates and marijuana are not likely to result in the kind of behavior you describe.
