Terpenes in 30 Seconds
Terpenes are aromatic compounds produced by plants — they're what makes a lemon smell like a lemon, a pine tree smell like a pine tree, and a cannabis flower smell like, well, cannabis. They're not unique to hemp; terpenes are found in fruits, flowers, herbs, and trees throughout the plant kingdom.
What makes terpenes interesting for CBD and cannabis users is that they appear to do more than just provide aroma. A growing body of research suggests terpenes interact with cannabinoid receptors and influence how your body processes CBD and THC. This is a key component of the "entourage effect" — the theory that whole-plant cannabis extracts work better than isolated cannabinoids.
When you see a CBD product labeled "full-spectrum" or "broad-spectrum," terpenes are a significant part of what's in there alongside the cannabinoids. When you see "isolate," the terpenes have been removed.
The Major Cannabis Terpenes
Cannabis produces over 200 different terpenes, but a handful dominate most strains and products. Here are the ones you'll encounter most often.
Myrcene
Aroma: Earthy, musky, herbal — like cloves. Also found in: Mangos, lemongrass, hops. Associated effects: Relaxation, sedation. Myrcene is the most abundant terpene in most cannabis strains and is strongly associated with the "couch-lock" effect of indica-dominant varieties. It may enhance CBD's calming properties.
Limonene
Aroma: Citrus, lemon, orange. Also found in: Citrus rinds, juniper, peppermint. Associated effects: Mood elevation, stress relief. Limonene is the second most common terpene in cannabis and is associated with the uplifting, energetic qualities of sativa-leaning strains. Preclinical studies suggest anti-anxiety and antidepressant properties.
Linalool
Aroma: Floral, lavender, sweet. Also found in: Lavender, coriander, birch bark. Associated effects: Calm, relaxation, potential anti-inflammatory. Linalool is what gives lavender its calming reputation — and it plays a similar role in cannabis. It's often present in strains used for sleep and anxiety support.
Alpha-Pinene
Aroma: Pine, fresh, sharp. Also found in: Pine needles, rosemary, basil. Associated effects: Alertness, memory retention. Pinene is the most common terpene in nature and may counteract some of THC's memory-impairing effects. It's associated with clarity and focus in cannabis strains.
Beta-Caryophyllene
Aroma: Spicy, peppery, woody. Also found in: Black pepper, cloves, cinnamon. Associated effects: Anti-inflammatory, potential pain relief. Unique among terpenes, beta-caryophyllene directly binds to CB2 receptors in the immune system — making it function somewhat like a cannabinoid itself. It's often present in strains used for discomfort.
Humulene
Aroma: Earthy, woody, hoppy. Also found in: Hops, sage, ginseng. Associated effects: Appetite suppression, anti-inflammatory. Humulene is closely related to beta-caryophyllene and gives beer its characteristic hoppy aroma. It's one of the few terpenes associated with appetite suppression rather than the munchies.
The Entourage Effect
The entourage effect is the theory that cannabinoids (CBD, THC, CBN, CBG) and terpenes work synergistically — meaning the combined effect is greater than the sum of individual parts.
A 2011 review in the British Journal of Pharmacology documented multiple ways terpenes can modify cannabinoid activity. Myrcene may increase the permeability of cell membranes, allowing cannabinoids to be absorbed more efficiently. Limonene may elevate serotonin levels, amplifying CBD's anxiety-reducing effects. Beta-caryophyllene binds directly to CB2 receptors, adding its own anti-inflammatory contribution.
This is why full-spectrum and broad-spectrum CBD products often produce more noticeable effects than isolate at the same CBD dose. The terpenes aren't just along for the ride — they're actively participating in the therapeutic experience.

How to Use Terpene Information
When choosing CBD products: Full-spectrum and broad-spectrum products naturally contain terpenes from the hemp plant. Some brands publish terpene profiles alongside their cannabinoid lab results — if you find a product whose effects you like, the terpene profile can help you understand why and find similar products.
When choosing cannabis strains: Terpene profiles are often more predictive of a strain's effects than the indica/sativa classification, which is primarily about plant structure rather than chemistry. A "sativa" high in myrcene may feel more sedating than an "indica" high in limonene. Check our strain finder to match terpene profiles to your desired effects.
When evaluating quality: Terpenes are volatile — they evaporate easily when exposed to heat, light, and air. A CBD product that smells strongly of hemp likely has a well-preserved terpene profile. Products that smell like nothing may have lost their terpenes during processing, reducing the entourage effect even if labeled "full-spectrum."
Terpenes Beyond Cannabis
Because terpenes are found throughout the plant kingdom, you're already consuming them daily. The essential oils used in aromatherapy are concentrated terpene extracts — lavender oil is rich in linalool, citrus oils are rich in limonene, and eucalyptus oil is rich in eucalyptol.
Some CBD brands add terpenes from non-cannabis sources to their products to create specific effect profiles. A sleep formula might add extra linalool and myrcene from lavender and hops. An energy formula might add extra limonene and pinene from citrus and pine. This is sometimes called "botanical terpene enhancement."
The cannabis plant's unique contribution is producing dozens of terpenes simultaneously alongside cannabinoids — creating a natural entourage effect that's difficult to replicate by adding individual terpenes to an isolate.
Frequently Asked Questions
Do terpenes get you high?
No. Terpenes are not intoxicating. They may influence how a high feels (by modifying cannabinoid activity), but they don't produce psychoactive effects on their own.
Are terpenes safe?
Terpenes are generally recognized as safe (GRAS) for ingestion at the concentrations found in food and supplements. You consume terpenes every time you eat a mango, smell a pine tree, or season food with herbs. At extremely high concentrations (as in some poorly formulated vape products), certain terpenes can irritate the lungs — but this isn't a concern with standard CBD oils and gummies.
Can I buy terpenes separately?
Yes. Isolated terpenes are available from specialty suppliers and some cannabis accessory retailers. Some people add terpenes to CBD isolate products to create a custom entourage effect. However, working with concentrated terpenes requires careful dilution — they're potent in pure form.
