Cannabis terpenes, explained.
Terpenes give cannabis its smell: citrus, pine, pepper, earth. They’re one of the most useful ways to tell products apart. Claims about what they do to how you feel are still mostly unproven.
What terpenes are
Terpenes are aromatic compounds made by many plants, from citrus trees to pine. In cannabis, they’re produced in the same tiny resin glands, called trichomes, that make THC and CBD. Most cannabis terpenes fall into two groups: lighter monoterpenes and heavier sesquiterpenes.
Terpenes are why two products with similar THC can smell completely different. Studies of commercial cannabis suggest that aroma often drives whether a product gets labeled indica or sativa.
Common cannabis terpenes
| Terpene | Aroma | Also found in |
|---|---|---|
| Myrcene | Musky, herbal, like fresh hops | Hops, lemongrass, bay |
| Limonene | Citrus, lemon-like | Citrus peel |
| Beta-caryophyllene | Spicy, peppery | Black pepper, oregano, basil, cinnamon |
| Alpha-pinene | Pine, fresh and woody | Pine and other conifers, rosemary |
| Linalool | Floral | Lavender, basil, bergamot |
| Humulene | Descriptions vary | Hops, where it was first identified |
You may also see terpinolene on labels. Research on commercial cannabis found that products high in terpinolene were more often labeled sativa than other products were.
Terpenes on a California label
Terpenes are optional on labels. When a producer lists them, the lab’s certificate of analysis has to confirm them. Many labels show only the top few. Compare them the way you’d compare aromas.
Terpenes are also delicate. A study of stored cannabis found they decreased rapidly under every storage condition tested. Fresh, well-stored products keep more of their aroma. See our storage guide.
Do terpenes change how cannabis feels?
You’ll often hear that myrcene is relaxing or limonene is uplifting. Here’s what the evidence actually shows:
- The “entourage effect” is the idea that terpenes and cannabinoids work together to shape cannabis’s effects. It was proposed in a 2011 review as a possibility worth studying.
- Lab tests haven’t found it at cannabinoid receptors. Two separate studies found that common cannabis terpenes didn’t activate CB1 or CB2 receptors, or change how THC acted on them.
- One exception: beta-caryophyllene binds the CB2 receptor in lab studies. That receptor isn’t the one behind the high.
- Human evidence is limited. A small 2024 study of 20 adults found that vaporized limonene reduced THC-related anxiety. It’s an interesting early result, not proof.
The fair summary: terpenes clearly shape aroma and flavor. Whether they meaningfully change effects in people is still being studied. We don’t sell any product on the promise that a terpene will make you feel a certain way.
Using terpenes to shop
- Note the top terpenes of products you liked, and look for similar profiles.
- Live resin and live rosin products are made from fresh-frozen plants, which is meant to preserve more aroma. See live resin vs. live rosin.
- Ask our team to compare a couple of options side by side.
