Earlier quoted context omitted.
I'm not saying you're wrong per se but what evidence do you have that there are no beneficial analogs and triggers for similar biochemical pathways that perhaps are not marked by a substantial or profound classically psychedelic experience?
It's much harder to prove a negative. What evidence do you have that there are? If you consider the way these drugs must be administered to be effective - with a co requisite therapy session - it seems obvious that the conscious effects are the beneficial ones.
There is sufficient evidence for both, and there is probably good reason to split them out (body and mind) and see them as different things that also work combined (body + mind). In this you might compare something like kambo to ayahuasca and ibogaine. They have many similar effects but have different ways of getting there (some more physical some more spiritual ,Kambo is probably not going to help with your childhood abuse, but it may help your high blood pressure, ayahuasca may help you process your childhood abuse and as a result lower your blood pressure.) If you look at something like 2cb vs lsd, lsd is found to be considerably more productive/creative than 2cb at subthreshold doses, but people often experience a much better "therapy trip" on high dose 2cb.
