Did anyone else notice that fully one third of examples of violent incidents possibly attributable to PCP in this column involved religion?
Are we looking in the wrong direction here? 
90% of them involved men.
Hmm…I run 2 websites specifically about dextromethorphan (DXM), and know a lot about that drug. DXM is a dissociative anaesthetic like PCP. DXM often causes religious ideation and delusions. Thus it wouldn’t surprise me that PCP does also. And, DXM has occasionally caused violence. I currently have on coricidin.org news reports of 2 murders committed by people abusing Coricidin. (Coricidin contains DXM and the anticholinergic drug chlorpheniramine maleate.) I also have’t got around to adding on that site news reports of a recent case where a man was convicted and sentenced to death for killing 3 people who while high on Coricidin. They were his ex-wife, son, and child that woman had from another man. He not only killed them, he even hacked out the hearts of all three of them. Dissociatives can cause extreme violence.
It doesn’t surprise me at all that dissociatives would cause that sort of violence, at least self-violence. I remember once taking too much Robitussin when I was about 8, and it’s certainly obvious why this type of drug is called “dissociatives” (or “dissociative anesthetics” as I think they used to be called). And I only took something like twice the normal dose, so I’m sure the effect wasn’t all that strong. But it sure had an effect – it was as though what I thought of as “me” was something completely separate from my brain and body – Cartesian dualism made glaringly real. I remember pinching myself and scratching myself and although I could feel it, and it hurt, it was like it was happening to an inanimate object rather than to me like it would normally feel. I didn’t progress to gouging out my eye or slicing off my face, but it doesn’t surprise me that people do that kind of thing on dissociatives.
