Is that actually the common thing to do amongst recreational psychadelics users (i.e. is there research backing this up)?
And how do these folks "understand the substance(s)"? We (humanity) know very little about how the brain works comparatively as far as I'm aware, and psychadelics research is further relatively lacking due to regulatory and funding constraints. Most resources I hear of just seem to be compilations of anecdata, frequently muddled with subjective remarks.
