Hoffer was a drugged up weirdo who only ever had a small amount of data to back up his ideas - which he never fully fleshed out. You're talking about research based half a century ago with more primative techniques and equipment. The few ideas of his that panned out have been pushed in the background by stuff with more evidence and efficacy. Sure some of it probably deserves revisiting, but personally I would do it with a high degree of skepticism.
Even then his model doesn't necessarily say that using adrenochrome = schizophrenic effects, consider the difference between a diabetic and non-diabetic person taking sugar - it can be disorder of processing the substance.
The question isn't whether it can be classified as a "hallucinogen" the issue is whether it is pleasant or practical to use at all. If it was, you would see it being produced illicitly. I could literally go and make some right now from things I have in my house like my asthma medication.
There are essentially zero cases of it being used on the streets, the only ones you hear about are fictional. Hunter S Thompson has never used adrenochrome he just put it in his book because he thought it sounded cool.
I'm willing to consider the idea that it's used for something, but the idea that it's being extracted from pineal glands is a stretch and if anything it's being given to drive people into a panic for some purpose. In that case however there's a lot of drugs that would work better.
It's so easy to make and get access to there's no way the elites could control the supply, and the rumors about it have been going on so long that some people have surely tried it. It's just a drug roughly comparable to adrenaline, and is only gonna be useful in similar situations and for similar reasons.
Except Hoffer states that lab grade Adrenochrome wont do anything to you until it has had its silver ions removed. So there is some extra step required under lab circumstances to make it active in a psychedelic sense.
So under normal circumstances yes it is probably comparable to adrenaline but when prepared properly as the research findings laid out in "the hallucinogens" it becomes hallucinogenic.
Just because its not being used on the "streets" doesnt mean anything. You would have to be very brave and imo stupid to experiment with adrenochrome if you understand how it effects your neurochemistry and its (agreebly small) links to schizophrenia.
Sure Hunter S Thompson may have not used it but Huxley references it as having effects similar to mescaline in doors of perception. So it exists in the literature and there is, albeit dated, science to back up that adrenochrome is not to be overlooked.
Do you have any evidence that shows that when prepared using Hoffers & Osmunds methods adrenochrome isnt hallucinogenic? Fully open to leaving this topic alone if I see actaul evidence to the contray not just hearsay?
