Atomic Breath Strain: Everything You Need to Know

The Atomic Breath strain has one of those names that tells you exactly what you’re getting before you even open the jar. Crack the bag and expect a wave of diesel, pepper, and garlicky funk that announces itself to the whole room.

Atomic Breath is an in-house cultivar from Grassroots, the cultivation brand owned by Curaleaf. It’s most consistently listed as Frosted Motorbreath RV04 x Modified Muffins #10. You may also see some menus simplify it to Motorbreath x Do-Si-Dos, but the Frosted Motorbreath and Modified Muffins cross is the better-documented lineage.

The Motorbreath side brings the loud Chemdawg and OG-style gas. The Modified Muffins side softens it with creamy, doughy sweetness and a hint of berry. Together, you get an Atomic Breath weed strain that smells like a fuel station and finishes like a bakery.

With THC reported between 20% and 30%, the Atomic Breath strain effects start with a clear, euphoric lift before settling into heavy body relaxation. It’s widely considered a late-afternoon and evening smoke.

Here’s what’s in the jar, and what’s worth knowing before you go looking for it.

If you want the Atomic Breath strain info in one place, here’s the cheat sheet:

• Strain type: hybrid, often described as indica-leaning because of its heavy body finish
• Genetics: Frosted Motorbreath RV04 x Modified Muffins #10
• Breeder: Grassroots (Curaleaf), through its in-house breeding program
• THC: typically 20-30%, with many retail batches landing around 22-25%
• CBD: under 1%, often 0-0.15%
• Terpene profile: beta-caryophyllene, limonene, pinene, linalool, myrcene
• Aroma/flavor: diesel, pepper, pine, garlicky funk, citrus, and creamy, doughy sweetness
• Effects: euphoric, clear-headed at first, then deeply relaxing and sedating at higher doses

The Atomic Breath strain terpenes are led by beta-caryophyllene, limonene, and pinene, with linalool and myrcene in support. That mix explains why it smells like gas and pine but still has a sweet side.

Beta-caryophyllene: This is usually the lead terpene, and it’s a big reason the jar smells like pepper, clove, and fuel.

Limonene: Limonene adds a bright citrus edge that cuts through the diesel. It’s commonly linked to mood elevation, which fits the happy, euphoric start of the Atomic Breath strain effects.

Pinene: Both alpha- and beta-pinene bring fresh pine and herbal, woody notes. That’s the piney exhale many users mention.

Linalool: Also found in lavender, linalool adds a soft floral, slightly creamy note. Research suggests it may help promote calm.

Myrcene: Usually lower in tested batches, myrcene still adds an earthy base and is commonly associated with relaxing body effects.

One Grassroots COA also listed caryophyllene oxide, guaiol, and humulene, which fill out the peppery, earthy, woody side. Atomic Breath strain terpenes can vary from batch to batch, so one jar might lean more gas while another leans more dessert. Either way, keep your jar sealed. This one is loud.

The Atomic Breath strain effects start with a fast, clear-headed lift and settle into deep, heavy body relaxation. It’s built for unwinding.

The primary effects of the Atomic Breath weed strain include:

• a quick, euphoric lift with a clear head
• a “lifted” feeling, often felt behind the eyes
• deep, calming body relaxation
• heavy sedation at higher doses
• a slow-creeping intensity that sneaks up on you

The Atomic Breath strain effects are reported to kick in fast. The head high hits first, with euphoria and mental clarity, and some people even feel a little social or energized early on.

Then the body side rolls in. Many users describe it as a creeper, building into a deep, calming relaxation that can turn sedating as the dose goes up. Duration commonly runs around 90 minutes to a few hours, depending on tolerance and the batch.

Best use cases: Late afternoon, after work, and evenings at home. It’s thought to help with unwinding.

Possible downsides: Dry mouth and dry eyes come standard. Because it creeps, it’s easy to overdo it, and low-tolerance users may feel overwhelmed or sleepy fast. Start low and wait.

Who enjoys Atomic Breath most: Gas lovers and experienced smokers who want a potent, body-heavy hybrid with a clear start. As for the Atomic Breath strain indica or sativa question, it’s a hybrid, but most people feel an indica lean by the end.

So what does a typical Atomic Breath strain review say? Most feedback comes from Reddit. Here’s the high-level read on Atomic Breath strain review sentiment:

• Praised for a loud, gassy nose with sweet, doughy notes underneath.
• Described as a creeper with strong, relaxing body effects.
• Noted for big, dense, frosty buds.
• Some batches arrive a little dry or need a better cure.
• Opinions are mixed, with some calling it gas and others calling it a miss.

The gas is the common thread in nearly every Atomic Breath strain review. So is the body high.

In one Atomic Breath strain review on r/PaMedicalMarijuana, a user picked up a Grassroots batch and rated it 8.1/10. They described light green buds covered in orange pistils, with a cake-and-dough smell and a subtle pine finish. It was a little dry but ground up nicely. On effects, they reported immediate relaxation, a super clear head, a strong feeling behind the eyes, and deep body effects. They called it a creeper and a heavy hitter, and gave it a “gas alert.”

Another Atomic Breath strain review came from r/ILTrees, where a longtime Grassroots buyer rated it 7.5/10. They described chunky, frosty buds with a gassy smell and a little sweetness, a smooth smoke, and a relaxing body high that didn’t glue them to the couch. They called it an easy after-work strain.

In r/FLMedicalTrees, a user wrote an Atomic Breath strain review on a batch testing at 30.5% THC and 3.38% terpenes. They’d seen mixed reviews, with some calling it gas and others calling it awful. They found huge, dense buds with mostly floral and diesel notes and a hint of citrus. The cure improved after a few days in a glass jar. The effects hit fast and hard, lasted about 90 minutes, and left them “flat out baked.” They rated it 8.75/10.

That’s the honest takeaway from every Atomic Breath strain review we read. Most users love the gas and the heavy body high, and many say the cure can vary by batch.

Pricing on the Atomic Breath weed strain depends on your state and the batch. Here’s the realistic range:

• Eighth (3.5g): $25-$50
• Quarter (7g): $50-$90
• Half ounce (14g): $90-$160
• Full ounce (28g): $160-$280

Premium indoor vs. budget comes down to the brand line and the batch. Grassroots tends to price toward the middle, while Curaleaf’s value-focused Find line can come in lower. Sales are common, so it’s worth checking your dispensary’s deals page before you buy.

The Atomic Breath weed strain is mostly found at Curaleaf dispensaries, sold under its Grassroots brand and its value-focused Find line. Availability varies by state and batch, so check your local Curaleaf menu first.

If you see the Atomic Breath strain Find version on the menu, it’s typically the more budget-friendly option. Whichever version you grab, look for a recent package date and a COA to confirm THC and terpene content. Since reviews note the cure can vary, a fresh batch makes a big difference.

The Atomic Breath weed strain is an in-house Grassroots cultivar, not a widely sold seed-bank strain. That means seeds and clones are hard to find, and detailed grow data is limited. If you come across a cut, treat it like a dense, resin-heavy, OG-leaning hybrid. Its Motorbreath side is known for heavy resin and vigor, while the dessert side adds tighter, chunkier buds.

Here’s general guidance for growing a strain like Atomic Breath:

• Difficulty: moderate; dense buds need careful humidity control
• Indoor vs. outdoor: indoors gives the most control
• Tent/space: a 4×4 tent handles 3-4 plants
• Lighting: strong, consistent light in flower supports resin and terpene production
• Temperature and humidity: around 68-80°F, with lower humidity through flower
• Training: LST or topping keeps the canopy even and improves airflow
• Veg period: about 4 to 6 weeks for most setups
• Feeding: feed moderately and ease off nitrogen heading into flower
• Flowering time: not widely published; similar OG-dessert hybrids typically finish in about 8 to 10 weeks
• Yield: moderate; published data is limited
• Pest and disease management: bud rot and powdery mildew are the main risks with dense colas; airflow is key
• Seeds available: not widely available, since it’s an in-house brand cultivar
