What in jenkem would cause hallucinations?

I just read on Snopes about a drug called jenkem, which is made from fecal matter and urine fermenting. A gas produced is inhaled and provides a hallucinogenic buzz. :dubious:
This seems very unrealistic sounding to me, but I am not able to find any information beyond anecdotal evidence.

Does anybody have the straight dope on this stuff? What chemical can be so easily produced to make a hallucinogenic drug from raw sewage, and why was it never discovered until the mid 1990s by some street kids in Africa?

a start

From your link:
“Sewer gas often has a “rotten eggs” smell, which comes from the hydrogen sulfide it contains. Exposure to low levels of this toxic chemical can irritate the eyes, cause a cough or sore throat, shortness of breath, and fluid accumulation in the lungs. Prolonged low-level exposure may cause fatigue, loss of appetite, headaches, irritability, poor memory and dizziness.”

Nothing in there that sounds like a high, except maybe the dizziness. Certainly nothing to cause hallucinations.

Where’s the puke smiley when you need it?

I love the images in this link. Plus the comments about the taste not going away.

I’ll admit, back when I was in high school I scored some good shit, but this is ridiculous.

I don’t know about this huffing fart gas thing, but feces does containe methane and indole, both of which can be psychoactive.

It reads like a spoof to me. Very reminiscent of the Brass Eye show on ‘cake’.

(Brass Eye was a satirical fake news show - in one episode, the creator managed to convince an assortment of celebrities to go on camera and make fools of themselves by warning against a supposed new drug called ‘cake’
