Reddit mentions of Psychedelic Information Theory: Shamanism in the Age of Reason

Note my disclaimer of huge grain of salt. I'm just regurgitating things that I've read and contextualizing it with my personal experience.

But neuroplasticity is not a concept I am simply speculating on. -http://en.wikipedia.org/wiki/Neuroplasticity

Drugs like psilocybin and LSD do what they do because they affect our neurochemical receptors, like serotonin.

There is evidence out there that these types of things happen such as recent treatments using these drugs to treat PTSD. You can go find these for yourself. At the least, a neuronal rewiring explanation is infinitely more rational than the sort of "the fungal/plant spirit healed me!" woo.

It's not my field of study. These are not my ideas. If you're looking for a stalwart defense of them, I encourage you to go read about them. For instance, a book like this one: http://www.amazon.com/Psychedelic-Information-Theory-Shamanism-Reason/dp/1453760172

Again, I would encourage you and everyone else to read material and come to your own conclusion. I just wanted to try to answer OP by regurgitating some of the information I have collected.

Psychedelic Information Theory

It presents information on a scientific theory of how psychedelics work. Not exactly what you were looking for, but I hear it's interesting.
