Understanding Cannabis Strains
Hello, lovely readers! If you’ve ever wondered whether a name like “indica”, “sativa” or a colourful variety name tells you exactly what a cannabis product is like, you’re in good company. It’s an easy place to start, but the story is a little more layered. 🌿
Today, we’re exploring what people mean by a cannabis “strain”, how varieties get their names, and why the plant’s measured profile can tell us more than a label. No pressure to memorise a glossary. Think of this as a friendly guide to looking beyond the name.
🌱 So, what is a cannabis strain?
“Strain” is the everyday term commonly used for a named variety of cannabis. The name may refer to a breeder’s line, a selection of plants, or a product that has become known by that label.
In plant science, you may also see the word cultivar. It describes a cultivated variety selected for certain inherited traits. And when we’re talking about its measured chemical make-up, chemovar is a useful term: it describes a chemical variety, based on compounds such as cannabinoids and terpenes.
A simple metaphor: the strain name is the book’s title, while the chemical profile is what’s actually inside the pages. The title can help us recognise a product, but it doesn’t tell the whole story. 📖

🪴 How do varieties get their names?
Breeders select plants with traits they want to continue, such as growth characteristics, aroma, or a particular cannabinoid profile. They may cross selected plants, grow the resulting seeds and choose plants that express the traits they’re looking for. Names are often chosen by breeders or producers, and there isn’t one universal naming system that everyone follows.
Some plants may also be propagated as clones. That can preserve a particular genetic line, but it doesn’t guarantee that every harvest will have an identical chemical profile. Growing conditions, harvest timing, processing and storage can all make a difference.
The name may have a story. It may hint at ancestry, aroma, or simply be a memorable label. But it isn’t a standardised promise about what a batch contains. Research published in Nature Plants found that “sativa” and “indica” labels did not reliably reflect overall genetic differences across the samples studied. Some labels were associated with variation in a small number of aroma-related compounds, rather than a clear-cut divide. (Watts et al., 2021) 🔍
🧪 Why the profile matters more than the name
In our earlier post, What Are Cannabinoids?, we looked at some of the compounds found in cannabis, including THC and CBD. A strain or variety may contain a mix of cannabinoids, and its aroma is influenced by compounds called terpenes.
The balance can differ between products, and even between batches sold under the same name. A research study examining cannabis samples found that the same names could be linked to different genetic and chemical profiles. That’s one reason a catchy label alone isn’t a dependable guide. (Study in Cannabis and Cannabinoid Research) 🧩
Where batch testing information is available, it can help you understand what was measured in that specific product. A certificate of analysis may list cannabinoids and, in some cases, terpenes. It tells us about the tested sample’s composition; it does not prove that a particular profile will create a specific feeling or health outcome.

Terpenes are part of the plant’s aromatic profile, but it’s wise to be cautious about confident claims linking an individual terpene to a predictable effect. Evidence is still developing, and a plant’s full profile is more complicated than a single compound.
That’s also a useful companion to our post What Is the Entourage Effect? The idea that different cannabis compounds may interact is interesting, but it shouldn’t be treated as a guarantee about how a particular named variety will affect someone. 🌼
🌿 Indica, sativa and hybrid: useful shorthand, not a crystal ball
You may have seen these terms used to describe plant varieties. As we explored in Indica vs Sativa vs Hybrid, they’re common labels, but they can’t reliably predict a product’s composition or response.
Think of them as broad signposts rather than a detailed map. The same label can cover products with different profiles, and people can respond differently to the same product too. So, if you’re reading about a variety, it helps to look for the actual product details rather than relying on a category or a reputation.

📋 A quick pros-and-cons look
| 🟢 Pros of strain names | 🔴 Cons of strain names |
|---|---|
| They can make a product easier to recognise in conversation. | A name isn’t a standardised chemical profile. |
| They may offer clues about a breeder’s lineage or selection. | The same name may be used for products with different profiles. |
| They can be a starting point for asking questions. | They can’t reliably predict effects, safety or suitability. |
| They’re familiar shorthand in cannabis discussions. | “Indica” and “sativa” labels don’t tell the whole genetic story. |
A name can start the conversation. It shouldn’t have to finish it. ✨
🇬🇧 A note for UK readers
In the UK, cannabis is not legal for recreational use. Cannabis-based products for medicinal use are prescribed within a specific legal framework. Initial prescriptions for many such products must be made by a specialist doctor on the GMC Specialist Register, with relevant expertise; NICE guidance also describes prescribing and monitoring responsibilities.
Prescribed medical cannabis patients receive specific products under specialist care. Their treatment isn’t simply a matter of choosing a popular variety name. If you’re a patient with questions about your medicine, speak with your prescribing specialist or care team rather than changing a product or dose based on a label.
CBD products are a separate topic, and a product’s CBD label doesn’t automatically make it a named cannabis strain or tell you its full contents. Always check the product information and seek qualified advice if you’re unsure, especially if you take medication. 🇬🇧
🐾 Buddy Says
“Let’s grow knowledge, not stigma. A name can be interesting, but asking what’s actually in a product is a much better conversation starter.” 🌱
💡 Buddy Tip:
If you’re comparing product information, look beyond the name. Check whether it gives a batch-specific cannabinoid profile, whether terpene data is provided, and who tested it. If the information isn’t clear, it’s perfectly reasonable to ask questions before making a decision. And if you’re a prescribed patient, keep product choices and changes within your specialist care plan.
🌼 Keep curious, keep it considered
Cannabis variety names can be part of the culture and history around the plant. They may offer a little context, but they aren’t a dependable shortcut to chemical composition or personal experience.
