Chemo
Chemo (UBC Chemo) is a rare, pure 100% indica born at the University of British Columbia in the 1970s from Afghani genetics. Developed with medical intent, it delivers heavy full-body relaxation, deep euphoria, and powerful sedation with THC levels reaching up to 29%. Best known for combating pain, nausea, insomnia, and appetite loss, Chemo is a cornerstone of Canadian cannabis history and one of the most therapeutically respected indicas ever cultivated.
The Short Answer
What kind of high is Chemo?
Myrcene-led and woody on the palate, most often reported relaxed and picked for meditation at night.
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
Okay, so I just settled into Chemo and... wow, this is what pure indica history feels like. It started with this warm, spreading euphoria — not a chaotic rush, just a smooth, intelligent calm that moved from the back of my head forward, like someone gently pressing the mute button on every stressor in the room. Within about fifteen minutes, I could feel my muscles releasing tension I didn't even know I was holding — shoulders, lower back, jaw — everything just... let go.
The myrcene in this one is doing serious biochemical work. It's crossing the blood-brain barrier efficiently and amplifying everything. My body feels heavy in the most pleasurable way — grounded, settled, anchored. There's a gentle limonene brightness keeping the mood elevated rather than dark, which is sophisticated for such a sedative-dominant profile. Caryophyllene is clearly at work too — there's a warm, anti-inflammatory sensation spreading through my joints that feels genuinely medicinal. This is what cannabis bred with therapeutic purpose feels like. It's a 1970s masterpiece — rare, intentional, and deeply effective.

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.

Chemo (UBC Chemo): The Legendary BC Indica
Chemo — also known as UBC Chemo, Kemo, or UBC Cut — is one of the most historically significant cannabis strains to ever come out of Canada. A pure 100% indica with roots stretching back to the 1970s, this rare and revered strain carries a legacy that few can match. Originally developed at the University of British Columbia (UBC) from Afghani landrace genetics, Chemo was reportedly cultivated with a specific medical purpose in mind: helping patients manage the devastating side effects of chemotherapy. That purpose is baked right into its name, and it remains one of the most medically respected indicas in cannabis culture today.
🧬 Genetic Heritage & Lineage
Chemo descends directly from Afghani — the ancient landrace strain prized for its heavy resin production, deep body effects, and sedative potency. Believed to have been developed around 1979 at UBC, the strain has been attributed to researchers seeking a therapeutic cannabis option during a time when medical cannabis was largely underground. It has since gone on to parent notable crosses, most famously Remo Chemo (UBC Chemo × Bubba Kush), popularized by Canadian cannabis cultivator Urban Remo and later distributed by Dinafem Seeds. Chemo itself remains a rare find, making authentic cuts highly sought after by collectors and medical users alike.
👃 Terpene Profile & Aromatics
Chemo's terpene profile is led by three powerful compounds:
- 🌿 Myrcene (dominant) — responsible for the deeply earthy, musky base aroma and the signature sedative body effect. Myrcene amplifies THC uptake across the blood-brain barrier, intensifying the overall experience.
- 🌶️ Caryophyllene — adds a spicy, peppery kick to the aroma while acting as a CB2 receptor agonist, contributing meaningfully to pain relief and anti-inflammatory effects without psychoactive impact.
- 🍋 Limonene — weaves a subtle citrus brightness into what is otherwise a heavy, dank nose, gently lifting the mood while rounding out the aromatic complexity.
The overall aroma profile is earthy, woody, pine, pungent, and skunky, with secondary notes of herbal spice, sweet florals, and chestnut. It's a complex, old-school nose that telegraphs serious indica potency before you even take a hit.
👅 Flavor Experience
On the inhale, you'll encounter rich woody and pine flavors with a pleasant earthy depth — like walking through a dense old-growth forest. The mid-palate brings sweet and herbal notes with a subtle spicy warmth from the caryophyllene. The exhale finishes smooth and full with a pungent, slightly floral aftertaste that lingers pleasantly. Some users detect hints of citrus and diesel on the back end, adding complexity to what is otherwise a classically old-school indica smoke.
🎯 Effects & Experience
With THC levels ranging from 18% to 29%, Chemo is no lightweight. Onset is relatively swift — within minutes you'll notice a warm euphoric wave washing over the mind, followed quickly by a heavy, full-body relaxation that settles into the muscles and joints like a weighted blanket. The high deepens over 20-40 minutes into profound sedation, making couch-lock a very real possibility for newer users. At peak, you'll likely feel:
- Deeply relaxed and physically anchored
- Euphoric and happy, with a calm, buzzy mental state
- Hungry — the munchies are strong with this one
- Sleepy — especially in higher doses
Duration typically runs 2-4 hours, and the comedown is smooth and restful, often transitioning naturally into sleep.
💚 Medical & Therapeutic Potential
Chemo's medical reputation is extraordinary. It may help with:
- Chronic pain, arthritis, migraines, and muscle spasms
- Nausea and vomiting — particularly useful for patients undergoing chemotherapy
- Appetite loss — one of the most reliable appetite stimulants in the cannabis world
- Insomnia — its sedative depth may support longer, deeper sleep
- Stress, anxiety, depression, and PTSD — the euphoric onset lifts mood before the body settles into calm
- Seizure management — referenced by several sources as potentially supportive
👁️ Visual Characteristics
Chemo buds are classically beautiful in an old-school indica way. You'll notice dense, chunky, medium-to-large nugs coated in a generous layer of milky white trichomes that give them a frosty, resinous sheen. Colors run through deep forest greens with olive and sage undertones, while rust-orange pistils curl throughout the bud structure. The overall appearance is compact, heavy, and sticky — a visual promise of potency.
🏆 Awards & Recognition
Chemo's child strain Remo Chemo earned significant industry recognition:
- 🏆 1st Prize, Indica Category — 2017 & 2018
- 🏆 1st Prize, Smell Category — 2018
- 🌟 Top 10 Strains of 2017
These accolades speak directly to the exceptional quality of the UBC Chemo genetics at its core.
📜 Cultural Context & Consumer Considerations
Chemo holds a special place in Canadian cannabis history — born at a university, designed to heal, and preserved through decades of underground cultivation. It's best suited for experienced indica users or medical patients seeking serious therapeutic relief. Novices should start low and slow — this is a potent, sedating strain best enjoyed in the evening or night. Keep water nearby for dry mouth, and don't plan anything demanding after consuming.
