Effects

Consumers report that Biohazard delivers a deeply relaxing experience, often accompanied by a notable cerebral surge within the first 15 to 30 minutes of consumption. The effects are known to be long-lasting, typically ranging from 2 to 4 hours, depending on the dose and individual tolerance. Due to its potency, a cautious approach is recommended, particularly for novice users.

Terpenes & Cannabinoids

This cultivar is known for its high THC content, generally ranging from 15-25%, with CBD levels below 1%. Its potency is a key characteristic, often leading to its designation as a high-THC cultivar.

Origins & Lineage

Biohazard is closely associated with the Chem and Diesel genetics waves that gained popularity in the 2000s and 2010s. While its exact parentage is not universally standardized, it is frequently described as Chem-family dominant, often crossed with Diesel, OG Kush, or Glue-type cultivars. This lineage contributes to its characteristic resin production, potent effects, and strong aromatics.

Cultivation

Biohazard typically exhibits vigorous vegetative growth and a pronounced stretch during the initial flowering weeks. It is known for producing dense, heavily frosted buds with strong apical dominance and moderate internodal spacing. Growers often note its robust trichome formation, making it desirable for extraction, but careful drying is necessary due to bud density.
