Indeed, it appears my own empirical investigations have something important to add to the new research and growing body of knowledge on psychedelics. 
For instance, and perhaps to the heart of what my personal experience offers, consider the following quote from page 386 of Pollan's book: "...(according to Hopkins researchers) ...psychedelic therapy creates an interval of maximum plasticity in which, with proper guidance, new patterns of thought and behavior can be learned."
That psychedelics may enhance neuroplasticity is something I had (independently) suggested in both my master's thesis and textbook. Realizing this "plasticity" effect, we might then ask: What are the "new patterns of thought and behavior" that can (or should) be learned? Exploring this question as well as proposing some answers is what this current work is all about, especially as revealed here.
So too other important questions arise: As more and more people try psychedelics (including the milder psychedelic of cannabis), what do we expect will happen when they return to the social system that very likely caused or at least significantly contributed to their sickness to begin with? Finally...
