1. What are Terpenes and Their Role?

Terpenes are a large and diverse class of organic compounds produced by a variety of plants, particularly conifers, and by some insects. They are responsible for the characteristic aromas of plants, such as the scent of pine forests or citrus fruits. In cannabis, terpenes contribute to the plant’s unique fragrance and flavor profiles and are believed to influence the therapeutic effects of cannabinoids like THC (tetrahydrocannabinol) and CBD (cannabidiol).

Terpenes are hydrocarbons, meaning they are composed of hydrogen and carbon atoms arranged in repeating isoprene units. Terpenoids, which are sometimes used interchangeably with terpenes, are modified terpenes that may contain oxygen or other elements.

According to research from the International Cannabis and Cannabinoids Institute, terpenes may offer therapeutic potential, especially in combination with cannabinoids. Ethan Russo, a neurologist and director of R&D at the institute, suggests that understanding the optimal combinations of terpenes and cannabinoids is crucial for harnessing the full therapeutic potential of cannabis.

2. What are the Key Functions of Terpenes in Plants?

Terpenes play several critical roles in the survival and reproduction of plants. These functions include:

• Protection Against Predators: Some terpenes have insecticidal or repellent properties, helping to protect plants from being eaten by insects and herbivores.
• Attraction of Pollinators: Many terpenes are aromatic and attract pollinators such as bees, butterflies, and other insects that are essential for plant reproduction.
• Defense Against Environmental Stress: Terpenes can protect plants from environmental stressors such as high temperatures, UV radiation, and oxidative stress.
• Signaling and Communication: Plants use terpenes to communicate with each other and with other organisms in their environment, for example, to warn neighboring plants of impending danger or to attract beneficial microbes.

Amber Wise, scientific director at Medicine Creek Analytics, emphasizes that a plant’s terpene profile can be significantly affected by environmental conditions. Factors such as temperature, growing medium, nutrients, and sunlight can all influence the types and amounts of terpenes a plant produces.

3. How Do Terpenes Differ From Cannabinoids?

While both terpenes and cannabinoids are chemical compounds found in cannabis, they have distinct structures and functions:

• Structure: Terpenes are hydrocarbons consisting of repeating isoprene units, while cannabinoids are more complex molecules that interact with the body’s endocannabinoid system.
• Function: Terpenes are primarily responsible for the aroma and flavor of cannabis and are believed to modulate the effects of cannabinoids. Cannabinoids, on the other hand, directly interact with cannabinoid receptors in the brain and body, producing a range of effects, including psychoactive and therapeutic effects.
• Psychoactivity: Terpenes are generally non-psychoactive, meaning they do not produce a “high.” THC is the primary psychoactive compound in cannabis, while CBD is non-psychoactive but has various therapeutic properties.
• Concentration: Terpenes are typically found in cannabis flowers at concentrations of 2–5%, while cannabinoids such as THC and CBD can be present at much higher concentrations, sometimes exceeding 20%.

Both terpenes and cannabinoids contribute to the overall therapeutic effects of cannabis through a phenomenon known as the “entourage effect,” which will be discussed in more detail later.

6. How Do Terpenes Interact With Cannabinoids?

Terpenes and cannabinoids are believed to work together synergistically to produce a wider range of therapeutic effects than either compound could achieve on its own. This phenomenon is known as the “entourage effect.”

According to Ethan Russo, the entourage effect involves complex interactions between terpenes, cannabinoids, and other compounds in cannabis. These interactions can enhance the therapeutic effects of cannabinoids, reduce their side effects, and alter their overall pharmacology.

For example, terpenes may influence the way cannabinoids bind to receptors in the brain, affecting the intensity and duration of their effects. Terpenes may also modulate the activity of enzymes that metabolize cannabinoids, altering their levels in the body.

Some specific examples of terpene-cannabinoid interactions include:

• Myrcene may increase the permeability of the blood-brain barrier, allowing more THC to reach the brain and enhancing its psychoactive effects.
• Linalool may counteract the anxiety-inducing effects of THC, promoting relaxation and reducing the risk of paranoia.
• β-Caryophyllene may enhance the anti-inflammatory effects of CBD by directly activating cannabinoid receptors in immune cells.

The entourage effect highlights the importance of considering the full chemical profile of cannabis, rather than focusing solely on the levels of THC and CBD. Whole-plant extracts that contain a diverse array of terpenes and cannabinoids may offer superior therapeutic benefits compared to isolated compounds.

7. What Factors Influence the Terpene Profile of a Plant?

The terpene profile of a plant, including cannabis, is influenced by a variety of factors, including:

• Genetics: Different varieties of cannabis have different genetic predispositions to produce certain terpenes. Some varieties may be naturally high in myrcene, while others may be high in limonene or pinene.
• Environmental Conditions: As mentioned earlier, environmental factors such as temperature, growing medium, nutrients, and sunlight can all affect the terpene profile of plants. Plants grown outdoors may have different terpene profiles than plants grown indoors under controlled conditions.
• Maturity: The terpene profile of a plant can change as it matures. Some terpenes may be produced early in the plant’s life cycle, while others may be produced later.
• Curing and Storage: The way cannabis is cured and stored after harvest can also affect its terpene profile. Improper curing or storage can lead to the loss of terpenes through volatilization.

According to David Heldreth, chief science officer at True Terpenes, specific treatments and conditions can be manipulated to influence terpene production, including lighting changes, fertilizer treatments, and the application of plant growth hormones and enzymes.

Understanding the factors that influence the terpene profile of a plant is essential for growers and manufacturers who want to produce cannabis products with consistent and predictable effects.

8. How are Terpenes Extracted and Used in Products?

Terpenes can be extracted from plants using a variety of methods, including:

• Steam Distillation: Steam distillation involves passing steam through plant material to vaporize the terpenes, which are then condensed and collected.
• Solvent Extraction: Solvent extraction involves using a solvent such as ethanol or butane to dissolve the terpenes from plant material. The solvent is then evaporated, leaving behind the terpenes.
• CO2 Extraction: CO2 extraction uses supercritical carbon dioxide to extract terpenes from plant material. This method is considered to be safe and efficient, as CO2 is non-toxic and can be easily removed from the final product.
• Cold Pressing: Cold pressing involves mechanically pressing plant material to extract its oils, which contain terpenes. This method is commonly used to extract terpenes from citrus fruits.

Once extracted, terpenes can be used in a wide range of products, including:

• Aromatherapy Products: Terpenes are used in aromatherapy to promote relaxation, reduce stress, and improve mood.
• Cosmetics and Personal Care Products: Terpenes are added to cosmetics and personal care products for their fragrance and potential skin-benefiting properties.
• Food and Beverages: Terpenes are used as flavoring agents in food and beverages, adding unique aromas and tastes.
• Cannabis Products: Terpenes are added to cannabis products such as tinctures, vape oils, edibles, and topicals to enhance their aroma, flavor, and therapeutic effects.

According to Randy Reed, president of Olala, a recreational-cannabis company, the extraction method used can significantly impact the quality and composition of the final product. Olala uses a multiphase carbon dioxide extraction technique with ethanol modifiers to extract cannabinoids and terpenes from fresh cannabis flowers, allowing them to control the amount of each ingredient added back into their products.

9. What are the Concerns About Vaping Terpenes?

While vaping terpenes is becoming increasingly popular, there are some concerns about the potential health risks associated with this practice.

Amber Wise, scientific director at Medicine Creek Analytics, warns that very little is known about the effects of vaping terpenes or the degradation products that they might form after high heat exposure. Terpenes are highly reactive molecules that can isomerize and interact with oxygen when heated, potentially forming harmful compounds.

Some specific concerns about vaping terpenes include:

• Lung Irritation: Vaping terpenes can cause lung irritation and inflammation, especially at high concentrations.
• Allergic Reactions: Some people may develop allergies or sensitivities to terpenes, leading to skin rashes, breathing difficulties, or other allergic reactions.
• Formation of Harmful Compounds: Heating terpenes can lead to the formation of harmful compounds such as formaldehyde, which is a known carcinogen.
• Lack of Regulation: The vaping industry is largely unregulated, meaning that there is little oversight of the quality and safety of vape products.

Jeff Raber, cofounder and CEO of the Werc Shop, emphasizes the importance of using safe thinning agents in vape oils. Some companies use thinning agents such as propylene glycol, polyethylene glycol, or vegetable glycerin, which can emit formaldehyde when heated.

Given the potential risks associated with vaping terpenes, it is important to exercise caution and to only use high-quality products from reputable manufacturers. It is also advisable to start with low concentrations of terpenes and to monitor your body for any adverse reactions.
