Well yes, when it was first studied they called it a "model psychosis" because it gave one temporary psychosis which then wore off.

The tipoff is that absolute certainty that you get in your thinking.

It seems as if "the veil has been lifted," and we suddenly "see the connections." Our mind seems sharper, more analytical, etc. Quite compelling.

I remember once, that I wanted to record the "great thoughts" that I had, while tripping, so I kept a notebook nearby, and wrote it all down.

Upon coming down, I read the notebook, expecting to be wowed.

I was. It was pure gibberish.
