Hazmat OG strain guide
Hazmat OG is a hybrid from Archive Seed Bank, a cross of Chem 91 and Face Off OG. True to the name, it smells loud: diesel, lime and a sharp, funky chem note. People tend to describe it as focused and energetic, and it lands near the top of THC listings.
Where does Hazmat OG come from?
Sources agree that Hazmat OG comes from Archive Seed Bank in Oregon, crossing Chem 91 with a backcross of Face Off OG. Chem 91 is one of the original Chemdawg cuts, the line behind many diesel strains.
One thing to know: a different strain from a breeder called The Fire Department also uses the Hazmat OG name, with its own indica-leaning genetics. Most listings and this guide refer to the Archive version.
What does Hazmat OG smell and taste like?
Expect fuel first. Descriptions mention strong diesel, a squeeze of lime and a skunky, earthy funk, and the breeder itself jokes about an oniony chem smell. It is not a sweet strain.
Published terpene results put myrcene first, followed by caryophyllene and limonene. Myrcene brings the earthy base, caryophyllene a peppery bite and limonene the citrus. Reviewers often say the flavour tastes like a classic OG with a Chemdawg edge.
Hazmat OG effects: what people report
People most often describe Hazmat OG as focused, creative and energetic, with a clear head rather than a heavy one. Some mention a euphoric, uplifted mood, and one reviewer called it a good start to the day. That is a bit unusual for an OG, so expect some variation between batches.
These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry mouth and dry eyes are the most common complaints.
How strong is Hazmat OG?
Hazmat OG is a very high-THC strain. Listings put it at about 27% to 29% THC, with very little CBD, and one strain database suggests it for more experienced consumers.
If you haven't tried it, start with a small amount and wait before having more. Always go by the THC and CBD numbers on your product's label, and see our guide to THCA vs THC for what those numbers mean.
Buying Hazmat OG in Canada
Because two different strains share the name, check the label or producer notes for the lineage if that matters to you. Different producers also grow different cuts.
You might find it as dried flower, pre-rolls or concentrates. Check the THC and CBD numbers and the packaging date, since fresher flower keeps more of its loud diesel smell.
Hazmat OG vs Face Off OG
Face Off OG is one of Hazmat OG's parents, a heavy OG Kush type with a piney, earthy, fuel smell. Hazmat OG keeps the OG base but adds the sharp diesel and lime of its Chem 91 side. The bigger difference is in how people describe them: Face Off OG is usually called relaxing and heavy, while Hazmat OG gets called focused and energetic. If you want a classic heavy OG, try Face Off OG. If you want the gas with a clearer head, Hazmat OG is the one.
