Cannabis Testing for : What They Are and Why They Matter


In the rapidly growing world of cannabis, one element that’s garnering massive attention is terpenes. They are aromatic compounds found in many plants, but in terms of cannabis, they play a remarkably significant role. 

From influence on aroma and flavor to therapeutic properties, terpenes are a vital component in understanding cannabis on a deeper level.

In this blog post, we will delve into the world of terpenes: what they are, why they are so essential, and what it means to test for them. Let’s step into the aromatic and therapeutic world of terpenes.

What are Terpenes?

Terpenes are naturally occurring chemical compounds found in plants and some animals, responsible for the aromas, flavors, and even colors associated with various types of vegetation. They are aromatic compounds that play a significant role in the cannabis plant, as they contribute to the plant’s unique aroma and flavor profile, as well as its potential therapeutic properties.

Terpenes are produced in the trichomes of female cannabis plants. Trichomes are sticky, translucent glands that cover the surface of buds and serve as a defense mechanism against herbivores and insects. Moreover, terpenes are created to help plants in a variety of other functions, such as attracting pollinators, repelling predators, and improving overall plant health.

Aside from cannabis plants, terpenes are also found in many other plants like fruits, flowers, and herbs. Some examples include limonene in citrus fruits, pinene in pine trees, and linalool in lavender.

Understanding the Importance of Terpenes

However,Terpenes are a major part of the therapeutic properties of plants and fruits, and they play a significant role in the benefits of cannabis. Here are key aspects to understanding the importance of terpenes:

Terpenes are not just proponents for smell and taste in plants, but they also have a wide range of health benefits such as:

  • Anti-inflammatory: Some terpenes show anti-inflammatory effects, which can aid in pain relief.
  • Antioxidant: Certain terpenes act as antioxidants, preventing damage to cells by free radicals.
  • Antibacterial: Some terpenes also have antibacterial properties, helping fight off harmful bacteria.

Influence of Terpenes on the Effects of Cannabinoids

Terpenes and cannabinoids work together in a unique way. Also, they have a synergistic relationship, where they can enhance or modify the effects of each other:

  • Interaction with the body’s endocannabinoid system; terpenes may affect how cannabinoids interact with the system’s receptors.
  • Altering the psychoactive impacts of certain cannabinoids.
  • Enhancing health benefits of cannabinoids.

Common Terpenes in Cannabis and Their Effects

In this discussion, we delve deeper into the most common terpenes found in cannabis and examine the unique characteristics and effects associated with each.


Myrcene is one of the most common terpenes found in cannabis. It has:

  • A dank, musky scent, often compared to earth and cloves.
  • Potential therapeutic benefits include anti-inflammatory and analgesic properties.
  • Been identified as a sedative and thus may promote sleep when present in higher amounts.


Limonene is a powerful terpene that:

  • Has a strong citrusy aroma.
  • Offers potential mood-enhancing and stress-relieving properties.
  • It may have antibacterial and antifungal properties.


Caryophyllene is unique among terpenes as it:

  • Has a spicy, peppery aroma.
  • It can interact directly with cannabinoid receptors in our body, particularly CB2 receptors, which primarily exist within our immune system.
  • Shows potential for pain relief, inflammation reduction, and even as a neuroprotective agent.


As the name suggests, Pinene:

  • Carries a strong pine scent.
  • Is believed to help with memory retention and alertness.
  • It may have anti-inflammatory properties.


Linalool is a terpene that:

  • Has a floral and spicy aroma. It’s also found in plants like lavender.
  • Is largely associated with stress relief and relaxation.
  • Has potential anticonvulsant properties, meaning that it might be beneficial for conditions like epilepsy.

Remember, the effects of these terpenes can vary based on the individual, the dose, the strain of cannabis, and other factors.

The Process of Cannabis Testing for Terpenes

There are three conventional methods that are typically used in cannabis testing procedures. These methods are:

1. Gas Chromatography (GC)

Gas Chromatography is a widely used chromatographic technique that can separate and analyze volatile substances in the gas phase. In GC, volatile substances are injected into the system and carried by an inert gas (carrier gas) through a column within an oven, where it separates out the different compounds based on their boiling point and affinity for the column’s stationary phase. GC is particularly useful for terpene analysis because terpenes are volatile and readily vaporize without decomposition.

2. High-Performance Liquid Chromatography (HPLC)

High-Performance Liquid Chromatography analyzes compounds that are not volatile or too thermostable. However,HPLC operates under high pressures, which increases the speed and resolution of the separation. In this method, a liquid sample is passed over a solid adsorbent material packed into a column using a flow of liquid solvent. Each compound in the sample interacts slightly differently with the adsorbent material, which causes different flow rates and thus separates the compounds as they flow out of the column.

3. Mass Spectrometry (MS)

Mass Spectrometry is a powerful analytical tool used to determine the makeup of a sample by measuring the mass-to-charge ratio of its ions. Also, the results are typically presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. MS can be used alone for a specific type of analysis, or in conjunction with the aforementioned methods (GC or HPLC) to further separate compounds, analyze the components, and confirm the structure and chemical properties of specific molecules. MS is not typically the first choice for terpene analysis but can provide the most accurate and detail-oriented results.

Uses of Terpenes in the Cannabis Industry

In the rapidly evolving cannabis industry, the utilization of terpenes has become increasingly important. Let’s explore some of the vital uses below:

  1. Terpene Profiling in Crop Cultivation

The first significant use of terpenes lies in crop cultivation. By employing terpene profiling, cultivators can isolate specific strains and manage the overall quality of their cannabis crops. This aids in ensuring product consistency and also paves the way for the development of new and improved strains.

  1. Product Formulation and Blending

Secondly, knowledge of terpenes proves crucial in product formulation and blending.Also, understanding unique terpene profiles allows professionals to create targeted cannabis products tailored to deliver specific effects or target particular ailments. But, this marks a significant shift towards personalized cannabis-based products.

  1. Retail Practices and Customer Decisions

Thirdly, understanding terpenes is gaining prominence in educating the retail practices of cannabis dispensaries. Also, by educating staff and consumers about the benefits and effects of different terpenes, they can help promote informed customer decisions.

  1. R&D Implications of Terpene Analysis

Lastly, terpene analysis plays a vital role in the realm of research and development within the cannabis industry. Such analysis aids in the investigation of potential medicinal applications of cannabis by enabling researchers to understand the contribution of different terpenes to various therapeutic effects.


In conclusion, terpenes play a crucial role in the therapeutic, aromatic, and flavorful aspects of the cannabis plant. Gaining a deeper understanding of these compounds not only unlocks a world of potential health benefits and enhanced experiences but also drives innovation and progress in the ever-evolving cannabis industry. 

To ensure the highest quality and the most accurate terpene profiles, also it is essential to test cannabis for terpenes and engage the expertise of reliable and trustworthy laboratories.
