Thanks for your feedback.
In my experience, those who use the term psychonaut to describe themselves (and those that others describe with it) have included most anyone who was into adventuring with psychedelics.
I've adjusted the title to just say (psychedelic) instead.
i have heard/seen it used in that context, but as a long time practitioner and student of chaos (and occult concepts in general) , it has always bothered me a bit. i like the term "psychonaut" but psychedelics blindfold the traveller and take them somewhere. that isn't "travel" so much as "kidnapping".
that said, i appreciate the adjustment, though i was certainly not suggesting any need to do so.
