Is There a Physical Change Going on in the Brain When I'm Imbuing Psychodelic Substances?

When you are in jesting a a psychodelic substance, you are not ingesting a physical subt substance. You are taking into your mind an area of mind that exists in consciousness, but outside your limited mind. And it should be no surprise to us that that can affect our mind any more than somebody else's thoughts can affect our minds. So yes, i think that just as a h that various meditations, yogas, various practices that we find in in the spiritual traditions, shamonic practices and taking psychodels is all valid intermediary steps.
