What are cannabis terpenes?

The term "cannabis terpenes" refers to the aromatic compounds found in cannabis plants that contribute to their distinctive smell and taste. While terpenes are often highlighted in marketing materials for their potential therapeutic benefits, it is important to understand what the current scientific evidence says about their role in cannabis and their effects on health. This guide provides a balanced overview of cannabis terpenes, based on available research and guidance, to help patients and carers make informed decisions.

Key takeaways

• Cannabis terpenes are aromatic compounds found in cannabis that contribute to its taste and smell, and may have some therapeutic effects.
• There are over 200 known cannabis terpenes, with variations between different cannabis strains.
• Some terpenes, such as pinene, are also found in other plants and may have potential benefits for respiratory health and cognitive function.
• The evidence for the therapeutic effects of cannabis terpenes is limited and often based on preliminary research or anecdotal reports.

Evidence base

Cannabis terpenes are a diverse group of compounds that are found in the resinous glands of cannabis plants. These compounds are responsible for the plant's unique aroma and flavor profile. While terpenes are often discussed in the context of their potential therapeutic benefits, the scientific evidence supporting these claims is limited. Most of the research on cannabis terpenes is still in its early stages, with many studies focusing on their chemical properties rather than their health effects.

Some terpenes, such as pinene, have been studied for their potential medicinal properties. Pinene, for example, is known for its ability to cross the blood-brain barrier and may have effects on memory and cognitive function. However, the evidence for these effects is not yet conclusive, and more research is needed to determine their true therapeutic potential. Similarly, other terpenes such as myrcene and limonene have been associated with potential benefits for pain relief and mood regulation, but these claims are largely based on preliminary studies or anecdotal reports.

The entourage effect, a concept that suggests that the combination of cannabinoids and terpenes may enhance the therapeutic effects of cannabis, is often cited in marketing materials. However, the scientific evidence supporting this idea is still limited. While some studies suggest that terpenes may modulate the effects of cannabinoids, the extent of this interaction and its clinical significance remain unclear. As a result, the role of terpenes in the therapeutic effects of cannabis is not yet fully understood.

What patients should know

Cannabis terpenes are a natural component of the plant and are often highlighted in product marketing for their potential health benefits. However, it is important to approach these claims with caution. While some terpenes may have beneficial properties, the evidence for their effectiveness in treating specific conditions is limited. Patients should be aware that the majority of research on terpenes is still in the early stages, and more studies are needed to determine their true therapeutic potential.

When considering the use of cannabis products, patients should be aware that the terpene profile can vary significantly between different strains. This variation means that the effects of a particular product may not be consistent across different batches or products. It is also important to note that the presence of certain terpenes does not necessarily mean that a product will have a specific therapeutic effect. The overall composition of the product, including the levels of cannabinoids such as THC and CBD, plays a significant role in determining its effects.

Patients should also be cautious of marketing claims that suggest terpenes can treat specific medical conditions. While some terpenes may have potential benefits, these claims are often based on preliminary research or anecdotal reports. It is important to consult with a healthcare professional before using cannabis products, especially if you have a medical condition or are taking other medications. A clinician can help assess the potential benefits and risks of using cannabis products and provide guidance on safe usage.

When to speak to a clinician

If you are considering using cannabis products for medical purposes, it is important to speak to a healthcare professional. A clinician can help assess your individual needs and determine whether cannabis may be a suitable treatment option for you. They can also provide guidance on the appropriate dosage and method of administration, as well as monitor for any potential side effects.

You should speak to a clinician if you experience any adverse effects from using cannabis products, such as changes in mood, sleep disturbances, or cognitive impairment. It is also important to consult with a healthcare professional if you have a pre-existing medical condition or are taking other medications, as cannabis may interact with certain drugs. Additionally, if you are unsure about the terpene profile of a product or its potential effects, a clinician can provide information and help you make an informed decision.

Red flags or review points to discuss with a clinician include:

• Any changes in mood, behavior, or cognitive function
• Adverse physical effects such as nausea or dizziness
• Interactions with other medications or supplements
• Uncertainty about the terpene profile or potential therapeutic effects of a product

Questions to ask a clinician

• What are the potential benefits and risks of using cannabis products with specific terpene profiles?
• How might the terpene content of a product affect its overall therapeutic effects?
• Are there any known interactions between terpenes and other medications or supplements?
