Has anyone tried this ? I'm Curious about it qualitatively

Yes, many times. And higher doses too.

My favorite setting for this is forested and hilly terrain, and I've done it mostly with chali, not so much with chacruna.

At the beginning there is the usual nausea and bowel movements, which is not the best time to hike, but after that, hiking can be a wonderful experience.

Qualitatively - euphoric, primal and a connection to nature.

If you realy want to feel one with the cosmos, if you want to intensely feel that bond with mother nature......go into nature on a powerfull psychedelic. It is an adventure.

I find mescaline, and related alks, more conducive to physical activity. Low dose tryptaminics are ok, however if mod-high doses are being used, phenethylamines are my preference for activity based tripping.
