Gas Leak is a hybrid that leans indica, most often listed as a cross of Chemdawg and Chem 91. True to its name, people know it for a loud fuel and chemical smell. Reports describe a light lift up front that settles into a heavy, relaxed body feel.

Where does Gas Leak come from?

The cross most often given for Gas Leak is Chemdawg and Chem 91, two of the gassiest names in the Chem family. One listing names a backcrossed Chemdawg cut (BX3) as the Chemdawg side.

The breeder is not well documented. One strain database notes that at least two other, unrelated crosses have been sold under the same name by different growers, so the Gas Leak you find may not all share one family tree.

What does Gas Leak smell and taste like?

Expect fuel first: diesel, chemical and skunky notes, with a spicy, herbal edge. Some reviewers also pick up a faint apricot sweetness under the gas.

Published terpene results put myrcene on top, followed by caryophyllene and humulene. Myrcene gives the earthy base, caryophyllene the peppery bite and humulene a woody, herbal note. The flavour follows the smell, skunky and spicy with a pungent finish.

Gas Leak effects: what people report

People often describe a short, clear-headed lift at the start, then a slow slide into body relaxation. Many call it happy and calm, and some find it sleepy as it wears on, which fits its indica lean.

These are reports, not promises. How it feels depends on the batch, how much you have and your own tolerance. Dry mouth and dry eyes come up most, and a few people mention feeling dizzy.

How strong is Gas Leak?

Listings put Gas Leak at roughly 15% to 23% THC, with very little CBD. That's a wide range, partly because different cuts carry the name.

Start low and wait before having more. The number on your label matters more than the strain name, and our guide to reading cannabis labels explains what to look for.

Buying Gas Leak in Canada

Because more than one cross is sold as Gas Leak, check the producer's description to see which lineage you're getting. Look at the THC and CBD numbers and the packaging date, since gassy strains lose some of their punch as they age.

You might see it as dried flower, pre-rolls or concentrates.

Gas Leak vs Chemdawg

Chemdawg is the older, better-documented strain and one of Gas Leak's listed parents. Both are built around diesel and chemical smells, but Chemdawg is usually described as more heady and cerebral, while Gas Leak's reports lean toward body relaxation and sleepiness. Chemdawg also has a long history behind it, while Gas Leak's origin is murky and its name covers several crosses. If you want the classic fuel strain, start with Chemdawg. If you want that smell with a heavier finish, Gas Leak is the one to look at.

Strains like Gas Leak

If you like Gas Leak, these share its fuel-forward character:

  • Chemdawg: a listed parent and the source of much of that diesel smell.
  • Chem 91: the other listed parent, sharp and chemical.
  • Stardawg: another Chemdawg descendant with a pungent, gassy nose.
  • Chem de la Chem: a Chem family strain for people who want even more fuel.

Autoflower strains: what they are and how they differAutoflowering cannabis switches from growing to flowering based on the plant's age, not on a change in daylight, because it carries genetics from Cannabis ruderalis. It stays smaller and finishes faster than a photoperiod plant, which usually means a smaller harvest.Can you fly with weed in Canada? Domestic flights and the borderYes on domestic flights, no across any border. CATSA allows cannabis in carry-on and checked bags on flights within Canada, and the 30 g public possession limit still applies. Taking cannabis out of Canada, even to a U.S. state where it is legal, is illegal.How long do edibles take to kick in?Health Canada says edibles can take 30 minutes to 2 hours to start working, with the strongest effects 2 to 4 hours in and effects lasting 4 to 8 hours. The wait is why the standard advice is to start low, go slow and not take more too early.
