Limonene is the terpene behind the smell of citrus peel. In cannabis, it gives strains a bright lemon, orange or lime aroma. It’s one of the most common terpenes in nature and is widely used as a food flavouring and fragrance. Its effects in people at the levels found in cannabis aren’t well established, though strains rich in it are often described as upbeat.

What research says
Most studies on limonene are in the lab or in animals, often at doses far higher than any strain contains. That research is why it’s discussed so often, but it doesn’t tell you how a particular strain will feel. Treat “uplifting” as a common description, not a promise.
Terpenes don’t get you high: THC does. And no single terpene reliably predicts how a strain will feel; the whole mix of cannabinoids and terpenes, your dose and your tolerance all play a part.
Tasting limonene
If you like citrus, look for flavour notes such as orange, lemon, lime or grapefruit. Lower-temperature vaping or dabbing (under about 200 °C) keeps more of the fresh citrus taste.
Why the amount varies
Terpene levels change with genetics, growing conditions, drying and curing, and storage. Two batches with the same strain name can smell quite different, so the nose, and a lab report when there is one, beats the name.
Common questions
What does limonene smell like?
Citrus peel: lemon, orange and lime.
Does limonene get you high?
No. Terpenes aren’t intoxicating; THC is what causes the high.
Which strains are high in limonene?
It varies by batch, even within a strain name. A lab terpene report is the only reliable way to know.
Is limonene in other foods?
Yes. It’s in citrus fruit peels and is used widely as a natural flavouring.
