Permanent Gas strain guide
Permanent Gas is a hybrid of Permanent Marker and Sour Diesel. As the name promises, people know it for a loud, fuel-heavy smell, and for a feel that starts bright and chatty before settling into something more relaxed. It's usually listed as a very high-THC strain.
Where does Permanent Gas come from?
The sources agree on the parents: Permanent Marker, a sweet, chemical-smelling hybrid from Seed Junky Genetics, and Sour Diesel, one of the best-known gassy sativas around. One strain database credits Seed Junky with Permanent Gas too, though other listings don't name a breeder, so that part is less settled.
Sources also split on how it leans. Some call it sativa-dominant and others call it indica-leaning, which may come down to different cuts. We list it as a hybrid.
What does Permanent Gas smell and taste like?
Gas comes first. Descriptions call it funky, diesel-heavy and sharp, the kind of chemical, fuel-forward smell that fills a room quickly. Under that, reviewers pick up sweetness, earth and a little pine.
The taste carries the diesel through, with a sweet, pungent side. Some describe grape candy and overripe berry under the fuel, likely from the Permanent Marker parent. No source we found publishes a terpene breakdown for this strain, so check the label if the producer lists one.
Permanent Gas effects: what people report
People most often describe Permanent Gas as energetic, uplifted and talkative at first, with a creative, euphoric spark. Many say it turns more relaxed after half an hour or so, with heavy eyelids and a full-body calm, especially in stronger 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 headache are the most common complaints.
How strong is Permanent Gas?
Permanent Gas is a very strong strain on paper. Listings put it around 27% THC, one reviewer shared a lab result of 31% THCa, and one grow listing claims an average as high as 35%, which is a breeder-style claim rather than a published test.
That's a lot, even for experienced people. Start with a small amount and wait before having more. The number on your label is the one that counts, and our guide to reading cannabis labels explains the THC and THCa figures.
Buying Permanent Gas in Canada
Read the lineage if it's printed: there are several Permanent Marker crosses with similar names, and they aren't the same strain. Look for Permanent Marker and Sour Diesel.
Check the THC and CBD numbers and the packaging date, since fresher flower keeps more of that loud gas smell.
Permanent Gas vs Permanent Marker
Permanent Marker is one of Permanent Gas's parents. Permanent Marker smells sweet, floral and chemical, a lot like its name, and has a strong, relaxed reputation. Permanent Gas swaps much of that candy sweetness for Sour Diesel's fuel, and reports describe a more energetic start. If you want the sweet, inky original, start with Permanent Marker. If you'd rather have it with a big hit of diesel, try Permanent Gas.
