Master Haze
Master Haze is a modern hybrid strain derived from the genetic crossing of Master Widow. As a cultivar classified within the current generation of cannabis breeding, it serves as a distinct point of departure from older genetic lines. The strain has demonstrated significant utility in both indoor and outdoor cultivation environments, where it requires a moderate level of technical skill to manage successfully. Growers can expect a 77-day flowering cycle and a high yield upon harvest.
The chemical profile of Master Haze is defined by a specific hierarchy of terpenes, led by myrcene as the primary aromatic compound, followed by caryophyllene and limonene as secondary and tertiary components. This combination generates a nuanced sensory experience, dictated by the interplay between the earthy qualities of myrcene, the subtle spice of caryophyllene, and the bright citrus notes of limonene.
In terms of clinical and recreational application, Master Haze is THC-dominant and is primarily utilized by those seeking relief from stress and pain or assistance with sleep. Users typically report a consistent profile of effects, characterized by feelings of relaxation, happiness, and an uplifted mood. The genetic legacy of this strain is evidenced by its notable offspring, Himalaya Haze, which carries forward the characteristics established by its parent.

Russo 2011: only terpene that is a selective full CB2 agonist (100 nM); Gertsch et al. 2008: acts as dietary cannabinoid; unique anti-inflammatory and gastric cytoprotective properties.
Russo 2011: increases serotonin in prefrontal cortex + dopamine in hippocampus via 5-HT1A; Johns Hopkins 2024: significantly reduced anxiety vs THC alone.
Effects
Reported effects — derived from terpene chemistry and cannabinoid profile.
relaxed
eveningPrimary endpoint of myrcene+linalool sedating combinations; GABA modulation is the dominant mechanistic driver.
