Agent BZ is a chemical weapon explored by the US military which induces overwhelming hallucinogenic states.

While there's a fair amount of data on the history of this subjects and the rough pharmacology, I'm interested to see if there are any subjective reports, first-hand experiences of those exposed to this substance.

I've tried searching around; Wikipedia doesn't seem to have anything, though there is a page for Agent BZ. Googling stuff like "Agent BZ subjective effects" or "subjective report" comes up with a lot of dense, dry medical journals talking in terms of observations, not subjective experience.

Any help would be appreciated, thank you!

    "overwhelming hallucinogenic states, first-hand experiences of those exposed to this substance": I can think of a few exposed to it and still in politics, science or (show)business... but, hey! no name-calling :D

  • Are you looking for "first person" vice "subjective"? Would that revision potentially get you a better answer?

    I don't think I have anything to add to the question, but that's an awesome screen name.

  • @MCW Yeah, I'm looking for a first person, subjective view. "I was exposed to/took this substance and this is what I experienced." Commented Jan 19 at 9:50

Given that Agent BZ is currently a pharmacological tool, I'm confident that there are. Given that it is a pharmacological agent, I'm confident that most of the first person records are going to be protected as Personal Health Information(PHI). It is possible you'll find a research paper on QNB that might contain some anonymized summaries.

Once considered a potential incapacitating agent for military applications, it is currently used as a pharmacological tool (a muscarinic antagonist known as QNB). It produces anticholinergic delirium, a non-specific syndrome of cognitive dysfunction, hallucinations, and inability to perform tasks. Inhalation exposure would likely involve an aerosolized solid. NIH.gov

I'd start with the two Ketchum references below, then I'd search on QNB

Several of the human exposures reported by Ketchum (1963) and Ketchum et al. (1967) were associated with high total response index (TRI) scores indicative of notable cognitive and behavioral effects and some motor-function effects but no apparent serious physiologic responses.

    This is a super valuable insight, I had no idea it was being actively used in a non-military setting! Thank you! Commented Jan 18 at 10:37
