Where Chemo Comes From
The common story is that Chemo started in 1970s Canada, possibly at the University of British Columbia, as a strain meant for patients dealing with chemotherapy side effects. That origin, and the alternate name UBC Chemo, are folklore: no records back it up, and AllBud lists the genetics as unknown.
What is documented is that Jordan of the Islands, a British Columbia breeder, carries a version of the strain. Leafly lists Captain Jack and WSU as offspring. Do not confuse it with Chemdawg, which is a separate line.
Chemo Effects: What It Feels Like
Reviewers describe a creeper: the effect builds slowly and then settles into a heavy, relaxed body high with sleepiness and strong appetite. AllBud mentions couch-lock and heavy sedation. Leafly rates its potency higher than average.
That makes it an evening strain. Newer consumers should give it time before taking more.
Chemo Terpenes, Aroma and Flavor
The aroma is woody, pungent and earthy with a pine edge. Tasters report chestnut, pepper and hoppy notes, and a sweet vanilla tone in some jars. AllBud notes the exhale can turn harsh.
Leafly lists caryophyllene as most abundant, then myrcene and limonene, which matches the peppery, woody and slightly citrus profile.
- Beta-caryophyllene: peppery and spicy, also found in black pepper and cloves
- Myrcene: earthy, musky and herbal, also found in mango and hops
- Limonene: bright citrus, also found in lemon and orange peel
Terpene levels vary from grower to grower and batch to batch, so check the lab label on the package. Learn more in our guide to cannabis terpenes.
Side Effects and How to Use Chemo
Dry mouth, dry eyes and dizziness are the common reports. The sedation is strong, so avoid driving and plan to stay put.
If you are new to Chemo, start with one small inhalation or 2.5 mg in an edible and wait before taking more; see our dosing guide.
Do People Use Chemo for Medical Reasons?
Leafly readers most often mention insomnia, pain and stress, and the strain’s name and lore tie it to nausea and appetite loss. These are anecdotal and not medical advice.
These are user reports, not clinical findings. For what research actually supports, see our cannabis health and research section, and talk to your doctor before using cannabis for a health condition.
