9, because only DMT was able to show me the existance of an entirely different realm of life/being.
Other Psychedelics only gave me vague notions of this realm, but DMT actually transported me into this realm completely.
I have found no psychedelic to immerse me as deeply into a truely other world than DMT has.
Seeing is believing and DMT made me see. I think that's why DMT has turned so many Atheists into spiritualists, religious people or at the very least openminded seekers/agnosts; When you SEE these divine amaterial realms and beings, there's no denying their existance anymore. Not without seriously contradicting your own perceptions and memories.
Allthough some Atheist Psychonauts will continue to hold on to their beliefs that there is no divine being/realm and that the only thing that is ultimately real is the material world; For them Seeing isn't believing. They saw the divine realms and beings, yet still denie it, "reasoning" these perceptions were merely delusions of their brain. But they seem to be a minority amongst Atheists. I think their belief system gets in the way. Their belief system makes them feel secure and in control. The intense fear of loosing that (false) sense of security and control seems to override their rationality: How rational is it, really, to dive into a world vastly different than our own, see it with your eyes, feel it with your body, hear it in your ears, come back from that realm and denie it's existance?
As far as I know most Atheists who became psychonauts have since gradually shed their denial of another, spiritual realm of existance and a creative, divine/supreme intelligence inhabiting & creating it. Or at least become more open to the possibility. Because after all for most of us human creatures, except for only the most stubborn and deeply in denial amongst us, seeing IS believing. And rightly so. Because why would a human frequently
smoalk DMT to travel to that other realm, if he/she firmly believes it doesn't exist?
If this realm doesn't exist, why then bother extracting and smoalking DMT to go there?
Go where?

I was once quite alot more Atheist too.(Rooted in my mistrust of organised religion which I still have)
Now I consider myself bouncing back and forth between Agnosticism & Spiritualism, much prefering Agnosticism.
Only DMT has been able to make that transformation on the deepest levels. Other Psychedelics only scratched the surface of those belief systems in me.
That's why I give DMT a 9.
