Sorry if it seems off topic but I just do not think you can talk about psychedelics without some recognition of where the potential therapeutic aspects are coming from due to the massive brain and conscious/sub-conscious changes.
I am not denying the mental effects and the often profoundly beneficial changes to personality and spiritual outlook that taking psychedelics can have.
In fact, personally, my main interest in reading about psychedelics has always been centered around their psychological, cultural and spiritual effects. Although I was born a decade too late, I have always been enthralled by the cultural movement of the 1960s: its exploration and expansion of consciousness through psychedelic drugs, and the effect these drugs had on the cultural and artistic expression of the time, and indeed their effect on the whole zeitgeist of the 1960s era. The cultural and social changes that were embryonic in the 1960s ended up profoundly transforming society and human culture, like for example the general shift to more liberal, tolerant and enlightened values we have witnessed.
I am not of course suggesting that psychedelics like LSD were entirely responsible for the 1960s and its cultural movements, but I think psychedelics played an important role.
In particular, I really loved the 1960s psychedelic and Eastern mysticism-fueled exploration of the outer reaches of the psyche, of consciousness and the human soul. That has always been my interest in psychedelics, for their exploratory potential (although as I mentioned, I was unfortunately generally too cowardly to take psychedelics myself).
The Greek-derived word psychedelic means "mind manifesting", and I feel so much of the ethos of the 1960s revolves around a manifestation of mind, consciousness, and soul.
By contrast, I find the inclinations and aspirations of society at present are a bit lacking in terms of its philosophical, ideological and spiritual dimensions. Society currently has become more machine-like, with less manifestation of mind and soul. At present, human activities and ambitions seem material, commercial and formulaic, like the commercial and formulaic musical dross pumped out by entertainment impresarios like Simon Cowell, or the bland commercial profit-driven films pumped out Hollywood over the last say 15 years.
At the moment it is hard to find any intuition-derived artistic expression that carries a perceptive message or ideology. It is mostly formulaic entertainment, carrying little cultural meaning, and not offering much exploration of the mind, human character, or the human condition.
In the 1960s and 70s, the activities of university students were often driven by all sorts of ideologies; nowadays students are mostly focused on personal financial reward (in part though out of necessity, since insidious factors such as high house prices make it hard to dedicate time and energy to anything else but material gain).
There has also been a shift in human character and personality away from
subjectivity: in the 1960s and 70s people were
characters, each person an expression their individual mind — the
subject himself was the center of his universe. In recent times, there has been a shift towards
objectivity of character: these days mindset is much more determined by external objective fact and external requirement; political correctness is one of these modern objective requirements imposed on human character; not suggesting this is a bad thing, but it definitely thwarts subjectivity).
Though with the current focus on materialism and factual objectivity, the world is doing well in terms of scientific and technological progress, including in medicine and the explosion of understanding of the human body and its metabolic pathways. I guess materialism is the zeitgeist of this age.
Anyway, enough of this rambling. Going back to using DMT to treat ME/CFS: I am not disputing the profound effects the psychedelics can have on the psyche; it's just my hunch that in the case of ME/CFS, this effect on mind is not the basis for DMT's temporary amelioration of ME/CFS symptoms; my hunch is that the basis is immunological.
One bit of suggestive evidence to support this hunch is the fact that these improvements in ME/CFS symptoms
are temporary; since we agree that psychedelics can produce significant long-lasting shifts in the mind, if the benefits for ME/CFS came from these mental shifts, then you would expect these ME/CFS benefits would to also be long-lasting, not the temporary benefits that are reported.
The trick is to get your hunches right about whether the cause of an illness like ME/CFS that has mental symptoms is psychological or physiological. A lot hangs on this.
Wessely almost certainly got it wrong in suggesting that ME/CFS is due to psychological rather than physiological factors, with tragic and catastrophic consequences for the whole of ME/CFS research.
Although I am prepared to accept it is possible that in a very small minority of ME/CFS cases, there could be some stress-related psychological factors playing a role; and in fact in these cases, the psychological effects of DMT, not just its physiological effects, could conceivably lead to permanent improvements in ME/CFS.
