GMO, also sold as Garlic Cookies, is the strain people either love or can't stand, because it smells like garlic, not fruit. Behind that savoury nose is a heavy, relaxed hybrid with a reputation for high THC, which has made it a favourite with experienced smokers.

Where does GMO come from?

GMO is usually described as a cross of Chemdawg and Girl Scout Cookies, and most accounts place it in the 2010s. Who bred it first is not well documented.

The name is commonly said to stand for garlic, mushroom and onion, a nod to its smell rather than anything genetic. Its Chemdawg side explains the fuel and funk, and the Cookies side explains the dense, frosty buds.

What does GMO smell and taste like?

GMO smells savoury and loud: garlic first, then fuel, onion and a little earthiness. There's almost no sweetness, which is exactly why fans seek it out.

Caryophyllene often leads its terpene results, adding pepper and spice, with limonene and myrcene further down. The flavour is pungent and savoury, and the smell sticks around, so an airtight container is worth it.

GMO effects: what people report

Reports lean heavily toward relaxed and sleepy, with a strong body feel that builds over time. Hunger comes up often, and many people save it for late in the day.

These are experiences people report, and they change with the product, the amount and your tolerance. Dry mouth and dry eyes are the most common complaints.

How strong is GMO?

GMO is one of the stronger strains you'll find. Published lab results usually put it around 22% to 28% THC, with very little CBD.

It's not a beginner strain. If you try it, start with a small amount and give it time. Your batch's THC is on the label, and with a strain this strong it's worth checking.

Buying GMO in Canada

GMO is widely available in Canada, mainly as dried flower and pre-rolls, and it's popular for hash and other concentrates too.

Look for a clear garlic and fuel smell when you open it. A faint smell usually means older product.

GMO vs OG Kush

Both carry that Chemdawg-style fuel, but they go in different directions. OG Kush adds lemon and pine and is known for a euphoric lift before the body feel. GMO swaps the citrus for garlic and onion, tends to test higher for THC and is described as heavier. If you love gas with some brightness, OG Kush is the classic. If you want savoury and strong, GMO is the one.

Strains like GMO

If GMO is your kind of strain, try these:

  • OG Kush: shares the Chemdawg-style fuel, with lemon and pine instead of garlic.
  • Wedding Cake: another Cookies-family hybrid, sweet instead of savoury.
  • Sour Diesel: the fuel side you like, with more energy.
  • Ice Cream Cake: just as heavy, with a creamy, sweet smell.
