Jack Haze
Jack Haze is a sativa-dominant hybrid (90/10) bred by 7ACRES, crossing the legendary Jack Herer with Super Silver Haze. Launched in 2019, it delivers a bright, focused, and euphoric high with a complex citrus, pine, and spicy herbal aroma. THC ranges 14–24%, making it versatile for both beginners and experienced consumers seeking daytime energy, creativity, and social spark.
The Short Answer
What kind of high is Jack Haze?
Terpinolene-led and sweet-pine on the palate, most often reported energetic and picked for stretching in the morning.
Terpenes decide how a strain feels — THC% only decides how strong the dose is. Here is the family, the chemistry behind it, and what people reach for it to do.
Terpenes are the aromatic compounds that shape the character of a high. The blend a strain carries — not its THC percentage — is what makes one feel bright and social and another heavy and sleepy, which is why the top three are listed rather than just the leader.
Terpene percentages belong to the jar, not the strain. They move with harvest timing, drying, cure and shelf age — the lighter ones literally evaporate. What holds steady is which terpenes lead, so that is what we rank.

The Experience
Professor High Says...
In-depth strain breakdown from Professor High, our AI cannabis expert
Oh wow — this is exactly what I needed on a Tuesday morning. I sparked a bowl of Jack Haze about fifteen minutes ago and my brain has just... shifted gears in the most elegant way. It's like someone turned up the resolution on my thoughts — everything feels sharper, more connected, more interesting. The terpinolene is doing exactly what it's supposed to: that fresh, almost electric mental lift that makes you want to start three projects simultaneously. But here's what's fascinating — it's not scattered. The pinene is holding everything together, keeping the mental activity organized rather than chaotic. My mood is unambiguously elevated. I feel genuinely happy — not floaty, not sedated — just present and engaged with the world. The caryophyllene adds a subtle warmth to the body that makes the whole experience feel grounded. I'm going to go write something now. Or call someone. Actually, probably both. This is the strain for people who want to think AND feel good doing it.

THC% tells you how strong. Terpenes tell you how it feels.
THC percentage is a property of the product in your hand, not of the strain. It shifts with the batch, the grower, the harvest, and how the flower was cured and stored — the same strain can test several points apart from two different jars.
Treat the ranges below as market context for what to expect on a shelf — then read the actual label on the product you are buying, and use the terpene profile to judge how it will feel.

Jack Haze: The Quintessential Daytime Sativa-Dominant Hybrid
Jack Haze is a sativa-dominant powerhouse that masterfully blends the legendary genetics of two cannabis hall-of-famers into something truly special. Bred by 7ACRES — a premium Canadian craft cannabis producer under the Supreme Cannabis umbrella — this strain was officially launched in 2019 and quickly carved out a reputation as one of the most invigorating and mentally stimulating cultivars in the Canadian market. With a composition of approximately 90% sativa / 10% indica, Jack Haze sits firmly in the cerebral, uplifting end of the spectrum.
🧬 Genetic Heritage & Lineage
Jack Haze descends from two iconic parent strains:
- Jack Herer — Named after the legendary cannabis activist and author, Jack Herer is itself a multi-award-winning sativa-dominant hybrid known for its blissful, clear-headed euphoria and complex spicy-pine aroma.
- Super Silver Haze — A three-time High Times Cannabis Cup winner, Super Silver Haze is a sativa icon celebrated for its long-lasting energetic effects and zesty citrus-earth profile.
By crossing these two legends in the 2010s, 7ACRES engineered a strain that amplifies the best of both worlds: the focused cerebral lift of Jack Herer combined with the sustained, sociable energy of Super Silver Haze. The result is a cultivar that feels both purposeful and euphoric, ideal for those who want to stay productive and present.
👃 Terpene Profile & Aromatics
Jack Haze features a rich, complex terpene profile with a total terpene content of approximately 1.61%. The dominant terpenes include:
| Terpene | Primary Effect | Aroma Contribution |
|---|---|---|
| Terpinolene | Uplifting, energetic | Fresh, floral, pine, citrus |
| Caryophyllene | Pain relief, CB2 agonist | Spicy, peppery, woody |
| Pinene | Alert, focused | Sharp pine, herbal, crisp |
| Myrcene | Subtle body relaxation | Earthy, musky, herbal |
| Ocimene | Uplifting, sweet | Sweet, floral, herbal |
| Limonene | Mood elevation | Bright citrus, lemon |
The aroma is a multi-layered sensory experience — you'll immediately detect bright citrus and pine up front, followed by warm spicy and herbal undertones, with subtle hints of diesel, tobacco, and floral notes rounding out the complexity. It's fresh, zesty, and invigorating from the moment you open the jar.
👅 Flavor Experience
On the inhale, you'll notice a crisp pine and lemon combination that's refreshing and clean. The mid-palate reveals spicy herbal and woody notes with a gentle sweetness that balances the sharper elements. On the exhale, a subtle diesel and earthy tobacco finish lingers pleasantly — complex without being overwhelming. The full flavor journey is bright, multidimensional, and deeply satisfying.
🎯 Effects & Experience
With THC ranging from 14–24%, Jack Haze delivers a wide spectrum of experience depending on your tolerance and dosage. Effects onset is typically fast and cerebral, arriving within minutes as an energizing wave of euphoria and mental clarity.
- 🧠 Mental Effects: Sharp focus, creative thinking, elevated mood, social talkativeness, and waves of giggly happiness
- ⚡ Energy: Sustained energetic drive without jitteriness
- 🌿 Physical: Minimal body sedation; the 10% indica genetics provide just enough grounding to keep the experience comfortable
The high evolves from an initial burst of uplifted euphoria into a sustained, focused creative flow — making it ideal for long work sessions or social adventures. Duration is typically 2–3 hours, tapering off smoothly.
🎮 Use Cases & Activities
Jack Haze is purpose-built for daytime use. You may find it particularly well-suited for:
- Creative work: Writing, art, brainstorming, music
- Social gatherings: Enhances conversation and laughter
- Morning routines: Coffee alternative energy boost
- Focused professional tasks: Research, strategy, analysis
💚 Medical & Therapeutic Potential
Jack Haze may help with stress relief, depression, anxiety management, fatigue, chronic pain, migraines, and inflammation. The combination of terpinolene and limonene may support mood elevation, while caryophyllene's CB2 receptor activity may provide gentle anti-inflammatory and pain-relief benefits.
👁️ Visual Characteristics
Buds are medium-to-large, elongated, and classically sativa in structure — lighter and airier than indica-dominant cultivars. You'll notice bright to medium greens with vivid orange pistils threading throughout. Trichome coverage is generous, giving the buds a frosty, resinous sheen that hints at the potency within.
📜 Cultural Context
Launched by 7ACRES in 2019 under Canada's regulated adult-use market, Jack Haze represents a premium craft approach to sativa genetics. It remains somewhat uncommon in dispensaries, making it a prized find for those who appreciate legendary lineage in modern form.
