In a 2011 survey of 292 clinical experts in Scotland, LSD ranked 4th lowest in personal harm and 6th lowest in social harm out of 19 common recreational drugs.[26]
I neglected to mention that LSD was ranked lower in harm than nicotine and alcohol, albeit we are talking about Scotland with the latter.
However, this LA County Hospital study was admittedly lacking in any control group, or long-term followup to define "extended", or for that matter any clear definition of what they mean by "psychosis".
It might also be helpful to note that this study period was in the immediate aftermath and locale of the Watts Riots, when we were also made to fear pretty much everything that went "Boo", at the same time that we were being confronted by the troubadour's messages and such.
Hollywood had me all revved up to go kill Commies at that time, and thankfully through Some Alternate Cultural Process, by the time I was of age, I started to figure out there was something rotten in Saigon. Among other things it was heroin (see the graph above). South Vietnam Air Force general and later President, Nguyen Cao Ky (by default a good Roman Catholic), was running one of the largest heroin rings, and his was selling it directly to American servicemen. But, at least he died a hero here in the USA.
About those ancient shamans and their Ayahuasca and so forth, is it possible that they had a similar agenda of inducing passivity & suggestibility in the flock? Although I wouldn't deny that shamans would also have enjoyed getting a 'buzz' as much as anyone else.
To the larger point, I'm not sure that you have yet proven the case about inducing passivity, directly at least. Maybe mass passivity, to the extent that the audience was under the influence, was indeed induced by the performances and external experiences the users underwent at the time.
If so, then this suggests that suggestibility can also be an agent of 'Good', whatever that is. That seems to be the basis of the work with the dying and PTSD. This might just as well be stated for shamen, generally, albeit that malfeasant practices have indeed been documented amongst
some of them. Indeed, for those who claim to have seriously studied the use of entheogens amongst indigenous tribal peoples, this is the rule rather than the exception.
My understanding of the ayahuasca experience is that it is not for the weak of heart, and done for the sake of 'enjoyment'. Such peoples are noted for have rites of passage (like Vision Quests), and as such I'm
guessing that those peoples with access to such compounds might use (have used) them amongst the laity, so to speak. But it is my understanding that a real shaman is the one who takes multiple 'trips' from time to time as needed, i.e. for addressing certain issues and not for the purpose of entertainment. These particular shamen report that the Cosmic Serpent informs them of such things as to what plants to use for medicines and specifically how to prepare them for optimal benefit. One theory is that this agency is the effect of the drug on the user's own neuronal DNA (the serpent) that then somehow speaks to its owner's mind. Instead, pharmaceutical companies send their researchers into the rain forest laboriously collecting samples to laboriously test for medicines and Dogod knows what, that is before Loren's friends finish burning down all the rain forests.
But in terms of Weaponized Anthropology, its interesting to note on the above graph how the CIA was forced to admit that it was complicit in the crack cocaine trafficking to urban American blacks, and that similarly how such as the British Crown and other elites proffitted handsomely from the opium and heroin trade. One of the primary responsibilities of American troops in Afghanistan was to protect the opium activity.
The shamen are generally willing to supervise one's experience, and I think that in the interests of Science that one of the group should undertake a 'trip' down there. I would happily volunteer but for my condition, and unfortunately Loren didn't move to Ecuador. That said, others have already done so and written about it.
