Jenkem is an alleged hallucinogenic recreational drug composed of noxious gas formed from fermented sewage. In the mid to late 1990s, several reports stated that Jenkem was being used by Zambian street children. The surfacing of the drug, or rumors of its existence, has caused at least one US municipality to amend its city ordinance regarding substances that cannot be legally inhaled to include organic substances.
