That quote comes from a longer talk, and is, I believe, out of context and misunderstood,
he's talking about experiences described at the start of his book "True Hallucinations",
about taking mushrooms, and meeting, what he said was the mushroom intelligence, a separate galactic spanning consciousness, or the other,
being chased by the FBI, he said he was "at the end of my rope", when they, the hive like mushroom over mind,
"recruited" him into their organisation,
being a storyteller, he creates a conversational like tone, talking about a place in the organisation with "a mouth like yours" and "background positions"
he even ends with a joke about eventually being "moved into public relations" and being there ever since!,
as in, his books, and giving talks on this subject of psychedelics and the "other" alien intelligence,
even the audience laughed ffs!!
I heard that talk years ago, a good few years later I heard about the agent McKenna conspiracy, and being interested, checked it out,
it was a youtube of some guy playing that talk and pausing it at that quote saying
"see!, he admitted he's an agent!"
I don't think so,
its not a very in depth conspiracy, because again, what could possibly have been the agenda, or plan?
that's how I see it, not deriding you personally, but what we believe we "know" is different, so maybe we both need to go back and research this, in order to argue our points,
(if you really want to, but I "know" its ballix)
as for being responsible and warning about drugs, fair enough, but have you read any of McKenna's books?,
we're not talking Timothy Leary or Hunter S Thompson here, or William Boroughs, or even cheech and chong!
his book "food of the gods", i think, is one of the most responsibly written books on drug use,
speaking against, what he called "synthetics", man made, like heroin, cocaine, alcohol, even refined sugar!,
and "electronic" drugs like TV, calling it the dominator drug par excellence
(and now we have hand held devices to hold our attention!)
he said NOT everyone should take psychedelics, they're not for everyone, only willing responsible adults,
brave psyconauts looking to explore the mind and all that,
(not everyone can be an astronaut or a fighter pilot either, as responsible adults we usually know our limits)
this is not taking e's and hugging everyone you meet,
psychedelics can be fuggin scary, definitely not for everyone,
some people might even be turned off the idea of taking them after reading his accounts,
it also traces specialist drug use amongst humans a long way back,
have you read it or any of his books?,
to just say "drugs are bad" and that's it isn't enough, yes some drugs are bad, and some are good,
its why asked you about your thoughts on medicines/pharmaceuticals, alcohol, caffeine,
everybody is different, you wouldn't take someone else's prescription, (well some might)
but you get what I mean, don't you? I mean, seriously
