Brief overview of terpenes in cannabis
Before diving into linalool specifically, let's first understand terpenes and their role in cannabis. Terpenes are aromatic molecules found in many plants, including cannabis.
Terpenes play a significant role in the plant’s survival by attracting pollinators and repelling predators. In cannabis, specifically, terpenes interact with other compounds found in the plant, like cannabinoids (THC and CBD), to create a synergistic effect known as the entourage effect.
The entourage effect suggests that using whole-plant formulations rather than isolating individual components results in different outcomes. There are over 200 different terpenes found within various strains of cannabis, each with its own unique flavour profile and characteristics.
What is linalool?
Linalool is a terpene, a class of organic compounds that are commonly found in plants, including cannabis. It is responsible for the distinct aroma profile of certain strains of cannabis.
Linalool has a chemical structure that is composed of two six-carbon rings known as benzene rings connected by an oxygen atom. This gives it a characteristic floral scent that is often described as lavender-like.
In addition to its use in plants, linalool has various applications in industries like cosmetics and perfumes. It can also be synthesised artificially for use in products like soaps and detergents.

Given its prevalence in both cannabis strains and other products, understanding the uses of linalool remains a subject of interest. In the following sections, we will examine what makes this terpene unique and why it has become so widely used in recent years.
Chemical structure and properties of linalool
Linalool belongs to the family of monoterpenes, which are composed of two isoprene units (C10H16). The chemical formula for linalool is C10H18O.

Linalool has a chemical structure consisting of two benzene rings connected by a central oxygen atom, classifying it as an alcohol. This structure contributes to its usefulness in different applications.
Linalool’s boiling point is 198°C. Depending on its form—either dextrorotatory or levorotatory—it can appear as a liquid or solid at room temperature. Its refractive index, which measures how light passes through it, ranges from 1.460 to 1.505, depending on its level of purity.
Common sources of linalool outside of cannabis
Linalool is a naturally occurring terpene found in various plant species, with some sources containing higher concentrations than others outside of cannabis. Its floral scent makes it valuable across multiple industries. Key sources of linalool include:
-
Flowers
- Lavender and rosewood are well-known for their fragrance profiles, to which linalool contributes significantly.
-
Citrus fruits
- Lemon and orange peels contain high levels of limonene, a compound that can be enzymatically converted into linalool.
- Limonene is also present in cannabis and can undergo similar conversions to boost linalool production in some strains.
-
Tree essential oils
- Ho wood and coriander essential oils hold significant amounts of linalool.
- Eucalyptus is another source of terpenes, including linalool.
This distribution across various plants highlights linalool’s versatility and the wide range of sources from which it can be obtained.
Scientific research on linalool
Linalool has drawn growing interest from researchers thanks to its distinctive scent and its influence on the aromatic and chemical character of various plants, including cannabis. Studies increasingly highlight its contribution to fragrance and its ecological functions.
A review published in Frontiers in Pharmacology (2018) explored the role of linalool in plant interactions, including its part in natural defence systems. Much of the research focuses on individual compounds or on plants other than cannabis, but it supports the idea that linalool plays an important role in how plants interact with their environment.
In cannabis, a 2020 review in Molecules identified linalool as one of several key terpenes that contribute to the aroma and distinctive character of different varieties. Some researchers suggest that terpenes like linalool may work alongside cannabinoids in what’s often called the "entourage effect."
Additional insights from the Journal of Cannabis Research (2021) indicate that varieties with a higher presence of linalool tend to offer a soft, soothing aromatic profile.
Although further research is ongoing, existing studies underline linalool’s role in shaping the unique scent and overall sensory impression of different cannabis varieties.
The role of linalool in cannabis
Linalool is one of the most common terpenes found in cannabis, recognised for its floral, lavender-like aroma with subtle spicy undertones. This compound plays a significant role in shaping the aromatic profiles that distinguish various cannabis strains.
