Fecal matter and urine are placed in a bottle or jar and covered most commonly with a balloon. The container is then placed in a sunny area for several hours or days until fermented.
The contents of the container will separate and release a gas, which is captured in the balloon. Inhaling the gas is said to have a euphoric high similar to ingesting cocaine but with strong hallucinations of times past.
Jenkem is the fermentation of raw sewage, the user will then capture and inhale the gas created during the fermentation process.
