Terpenes Explained: Myrcene, Limonene and More
What terpenes are, the ones you'll see most on cannabis labels, what they smell like, and why it's worth being sceptical of effect claims.

Open a jar of cannabis and the first thing you notice is the smell: citrus, pine, pepper, skunk, fuel. That smell comes from terpenes, aromatic compounds made by the cannabis plant and by plenty of others, from oranges to black pepper to lavender. More producers now list terpenes on labels, so it's worth knowing what they are, and what they aren't.
What terpenes are
Terpenes are the aromatic oils a plant produces. In cannabis they're made in the same tiny resin glands (trichomes) as THC and CBD. They give each product its particular smell and flavour, and they're a big part of why two products with the same THC number can seem so different in the jar.
Terpenes are also delicate. Heat, light and air drive them off over time, which is one reason storing cannabis properly keeps it smelling fresh.
The ones you'll see most often
| Terpene | Smells like | Also found in |
|---|---|---|
| Myrcene | Earthy, musky, herbal | Hops, mango, thyme |
| Limonene | Citrus, lemon, orange peel | Citrus rinds |
| Caryophyllene (beta-caryophyllene) | Peppery, spicy, woody | Black pepper, cloves |
| Pinene (alpha and beta) | Pine, fresh, sharp | Pine needles, rosemary |
| Linalool | Floral, lavender-like | Lavender |
| Humulene | Woody, earthy, hoppy | Hops |
| Terpinolene | Fresh, piney, slightly fruity | Lilac, apples |
Labels usually list the top two or three terpenes, sometimes with a percentage or a "total terpenes" figure.
What about effects?
You'll see claims online that a given terpene makes cannabis relaxing, energizing or "good for" something. Be cautious:
- Research on terpenes in cannabis is still limited, and most effect claims go well beyond what's been shown in people.
- Terpenes are present in small amounts compared with THC.
- How a product feels depends far more on THC and CBD, dose, format and you: your tolerance, mood and setting.
Terpenes vs. indica and sativa
Terpene profiles are one reason products feel different, but they don't line up neatly with indica, sativa or hybrid labels. Two "indicas" can have completely different terpene profiles. Indica vs. Sativa explains why those labels are a weak guide.
How to use terpene info
- Notice what you like. If you keep enjoying products high in limonene or pinene, that's useful to know when you browse.
- Keep notes. Product name, THC/CBD, top terpenes, how much you had and what you thought.
- Check freshness. A recent packaged-on date usually means a stronger aroma. Our label guide covers where to find it.
Why some products smell stronger
- Freshness: terpenes fade with age.
- Processing: some concentrates, such as live resin, are made to preserve more of the original terpene profile. Others, such as distillate, have most terpenes removed and sometimes added back.
- Storage: heat and air are the enemies. Keep jars sealed and cool.
When you're comparing products, terpene notes are a nice tiebreaker after THC, CBD and format. Creator's Choice lists product details on its flower and live resin pages.
