"The effects of DXO alone are (theoretically at least) more similar to ketamine than DXM"
To be honest with you, my first reaction is to say that claim is bull-shit. DXM has always given me a tooth-grinding, anxiety-filled, hellish experience. With ketamine, sometimes I have an experience that makes me feel psychologically raped, but at least I always gain wisdom. Ketamine is so much deeper. Shit, I wish DXO was like K! But, I highly doubt it!
