Terpenes in Cannabis: Myrcene, Limonene, Pinene, Linalool and Caryophyllene
What myrcene, limonene, pinene, linalool, caryophyllene and other cannabis terpenes are, what research does and does not show, and why product terpene profiles vary.

Overview
Terpenes are aromatic compounds, and they are responsible for cannabis's odors. [1] More than 100 have been identified in cannabis. [2] Other reviews count more than 150 across different varieties. [3] This page covers five well-known cannabis terpenes. Evidence labels: preclinical (cells/animals only), insufficient evidence, mixed and marketing claim. "Proper evidence not found" means we looked and found nothing usable. Essential-oil aromatherapy is covered separately in aromatherapy.Five terpenes and what the research says
| Terpene | What the reviews and papers say | Label |
|---|---|---|
| Myrcene | A 2024 systematic review lists relaxation as an exploratory finding. Myrcene was anti-inflammatory when applied to skin, but with CBD it did not add significant extra benefit. [4] | insufficient evidence |
| Limonene | The same review lists pain relief (D-limonene as an analgesic) as exploratory. [4] | insufficient evidence |
| Pinene (alpha and beta) | No evidence of protective effects against amyloid-related toxicity, though modest inhibition of lipid peroxidation was seen. [4] | preclinical |
| Linalool | Exploratory findings for sleep help and relief of exhaustion and mental stress. [4] | insufficient evidence |
| Beta-caryophyllene | In 2008 it was reported to bind to the CB2 receptor selectively and act as a CB2 agonist in cells, and to reduce an inflammatory response in normal mice but not in mice lacking CB2. [5] A 2020 binding study found only a possible weak CB2 interaction. [6] | preclinical, mixed |
The review abstract does not separate human findings from animal or cell findings, so we treat these as exploratory and do not apply them to people. A 2021 review proposes that these terpenes may contribute to anti-inflammatory and pain-related effects of cannabis, and says better understanding is needed. [3] Proper evidence not found for a cannabis terpene shown, in a trial in people, to change a health outcome.
Other terpenes you may see
Reviews also discuss alpha-humulene, caryophyllene oxide, nerolidol, phytol, valencene, borneol and eucalyptol. [7][3][4] The same caution applies: the 2024 review's own conclusion is that terpene enhancement of cannabinoid effects remains unproven. [4]The "entourage" idea
The proposal that terpenes and cannabinoids work together is explained, with its weak evidence, in cannabis chemistry. A 2020 lab study found no direct effects of five terpenes at CB1 or CB2, alone or with THC, CBD or 2-AG. [6]Terpenes in products
In 89,923 lab-tested US flower samples, THC-dominant products fell into three main terpene groups: high beta-caryophyllene and limonene, high myrcene and pinene, or high terpinolene and myrcene. [1] Most samples (87.4 percent of THC-dominant ones) belonged to the first two groups. [1] Terpene profiles differ from product to product, even among those sold under the same name; see cultivars, chemotypes and strain names. The FDA notes variability in other cannabinoid and terpene content among delta-8 products. [8]Safety notes
- Food-use status is not inhalation safety. Russo notes these terpenes are common in the diet and have been designated Generally Recognized as Safe by the FDA and other regulatory agencies. [7] That status does not tell us how safe they are when inhaled, and we did not find a source on that.
- Aromatic products. For general precautions with concentrated aromatic oils, see essential oil safety.
- Marketing. Terpene "effect charts" on packages are a marketing claim unless backed by trials in people. A large lab-based study found commercial labels do not reliably match chemical profiles. [1]
- Medicines. Cannabis can interact with other medicines. [9] See medication interactions.
Frequently asked questions
Do terpenes make cannabis relaxing or energizing?
Proper evidence not found. Reviews describe exploratory terpene findings but say additive effects with cannabinoids remain unproven. [4]
Does beta-caryophyllene act on cannabinoid receptors?
One 2008 study reported selective CB2 binding in cells, while a 2020 study found only a possible weak CB2 interaction. [5][6]
Are cannabis terpenes the same as essential oils?
Some terpenes are also in essential oils, but this page only covers what research says about cannabis terpenes. See what are essential oils.
Do products sold under the same name have the same terpenes?
Not reliably. A large analysis found distinct chemotype groups and variation even within products sharing a name. [1]
