The psychedelic experience seems to be located at the border between the mental and spiritual realms.
An interesting but dangerous place to be.
If psychedelics were a purely spiritual "technology", they would consistently produce a reduction of ego-supremacy, but they don't. They reduce the ego of some and further inflate the ego of others.
Go see your local shaman for evidence.
This isn't to say that psychedelics are good or bad, they are what they are, but they most certainly aren't a reliable cure for our spiritual ills.
