I wondered what would happen when all of these people are left without their drug of choice. Still searching for the answer. Lots of info in link.
Adrenochrome may cause irritability, apathy, visual and auditory hallucinations, acute schizophrenia, tachycardia, loss of concentration, paranoia, ambivalence, alterations in perception and estimation of time, difficulty in concentrating, relaxation, euphoria, giggling etc.
Methadone is NOT heroin; it is a substitute that is not claimed to be 'the same'. It's designed to give you 'some' of the feelings of heroin while also allowing you to gradually get off of the habit. Synthetic adrenochrome is, however, pure. Synthetic, in this case, simply means synthesized in a lab.
As the other poster said, there's absolutely no evidence to support the fantasy that there is a unique quality of 'adrenochrome' extracted from children. The fact that person 'a' said something, person 'b' referred to 'a' as a source, and person 'c' then says 'I've seen plenty of "Evidence" (from a and b) does not constitute rational scientific examination.
