Iraqi Haze is a modern hybrid strain produced by crossing Original Haze with Iraqi Pilgrim. The history of this specific cross remains undocumented, and there is no information available regarding the specific breeder or the exact timeline of its development. Given its genetics, the strain represents a deliberate effort to combine the traits associated with its parent lines into a single, cohesive hybrid.

The terpene profile of Iraqi Haze is broad, featuring a complex array of aromatics dominated by caryophyllene, followed by myrcene, limonene, pinene, humulene, ocimene, nerolidol, linalool, beta-pinene, guaiol, p-cymene, bisabolol, eucalyptol, camphene, and caryophyllene-oxide. This diverse chemical composition influences the sensory experience, contributing to a nuanced aromatic profile that reflects the presence of these fifteen distinct compounds. Its chemical expression is characterized by this specific hierarchy of volatile oils, which define the strain's olfactory and gustatory identity.

As a THC-dominant cultivar, Iraqi Haze is associated with effects that are consistently reported as relaxed, happy, and uplifted. These characteristics make it a functional choice for those seeking relief from stress and pain, or for patients looking for assistance with sleep. The strain is cultivated in both indoor and outdoor environments, offering a high yield despite a long flowering period of 100 days. While the cultivation process is considered of moderate difficulty, there are currently no recorded offspring for this variety.
