The Short Answer
What kind of high is 303 OG Kush?
Myrcene-led and earthy-coffee on the palate, most often reported relaxed and picked for sleep & bedtime in the evening.
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
As this hits, I feel a bright wave of euphoria roll in first — almost cheerful, like the Limonene is doing a little happy dance behind my eyes. Then, gradually, the Myrcene takes the wheel. My shoulders drop, my jaw unclenches, and a warm, syrupy heaviness spreads through my limbs. It's not an instant knockout — more like a slow tide pulling me toward the couch. Thoughts get pleasantly fuzzy around the edges, conversation feels easy but unhurried, and that diesel-pine exhale keeps reminding me this is classic OG territory. By the peak, I'm sinking into cushions with a dopey grin, fully present but delightfully unmotivated to move. This is a strain that teaches patience — the good kind of high that unfolds rather than slaps you.

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.

The Legend of 303 OG Kush
Named after Denver's iconic 303 area code, 303 OG Kush is a heavy-hitting indica-dominant strain born from a legendary pairing of West Coast genetics. With a genetic split of roughly 60% Indica / 40% Sativa, this Kush cross has earned a quiet but devoted following among those who know their OG lineage — and once you understand what's behind it, you'll see why.
🧬 Genetic Heritage & Lineage
303 OG Kush was created by breeder Zombo, crossing the legendary Pre-'98 Bubba Kush with the pungent, diesel-forward Chemdawg (referenced in some circles as Reservoir ChemDawg IC3). This combination pulls from two of cannabis breeding's most influential lineages — Bubba Kush's dense, sedating body-stone genetics fused with Chemdawg's sharp, fuel-like potency. The result is a strain that carries the DNA of West Coast royalty while carving out its own identity in Colorado's cannabis culture.
👃 Terpene Profile & Aromatics
The dominant terpene, Myrcene (around 0.52%), sets the tone with its classic musky, sedating undertones — the same terpene found in mangoes and hops that's associated with deep body relaxation. Close behind is Limonene (0.51%), lending bright citrus lift to counterbalance the heaviness. Rounding out the profile are Linalool (0.36%) for calming floral notes, Caryophyllene (0.27%) contributing peppery spice, and a touch of Humulene (0.14%) adding earthy depth. Together, you'll notice a complex nose of earthy, pungent diesel layered with pine, woody, and honeyed citrus accents, plus subtle coffee and herbal whispers underneath.
👅 Flavor Experience
On the exhale, 303 OG Kush delivers a multi-layered flavor journey. The first hit brings pungent diesel and pine, quickly followed by earthy, woody Kush notes reminiscent of classic OG phenotypes. Mid-palate, you'll pick up honey sweetness and citrus zest, while the aftertaste settles into nutty, coffee-like, and skunky notes that linger pleasantly on the tongue.
🎯 Effects & Experience
Expect a slow-building high that starts with a wave of happy, euphoric uplift before settling into deep relaxation and sleepiness. Some phenotypes also express creative and focused energy in the come-up, making the early effects surprisingly versatile before the indica-dominant body stone takes over. This is a strain that rewards patience — the peak arrives gradually and deepens over the following hour, ideal for evening sessions where you have nowhere else to be.
🎮 Use Cases & Activities
303 OG Kush shines during evening unwinding, stress relief, and relaxation sessions. Its sedating body effects make it a strong candidate for sleep aid use, while the initial uplift can support light creative work or unwinding conversation before the couch-lock sets in.
💚 Medical & Therapeutic Potential
Many reach for 303 OG Kush to help manage chronic pain, muscle tension, and insomnia, with the Myrcene-Caryophyllene combination believed to support both sedation and physical comfort. On the mental side, users report relief from stress, anxiety, and depressive symptoms, likely aided by Limonene's mood-elevating properties.
👁️ Visual Characteristics
Buds typically present as dense, forest-green nugs with hints of olive and deep purple, wrapped in a generous coat of frosty trichomes and fiery orange hairs — a textbook OG Kush appearance.
🏆 Awards & Recognition
303 OG Kush earned recognition for Best U.S. Concentrates in 2014, cementing its reputation as a strain valued not just for flower but for extraction quality.
⚠️ Consumer Considerations
With THC typically ranging from 12-20%, this strain suits intermediate to experienced consumers seeking a heavy-bodied evening experience. Novices should start slow given the sedating potency.
