Cannabis analysis to ensure product purity and quality


La seguridad del cannabis es una prioridad clave tanto para los productores como para los consumidores, y los análisis desempeñan un papel fundamental en este proceso. Discover the importance of cannabis analysis, also known as potency testing or cannabinoid profiles.

Why is cannabis testing crucial?

Cannabis testing is essential because consumers have the right to know the chemical composition and potency of the products they are using. We are talking about both medicinal cannabis and cannabis for recreational users. Additionally, cannabis analysis provides valuable information for those who carry out the cannabis production process, thus ensuring they know what they are handling.

Composition of cannabis, essential components

THC (tetrahydrocannabinol) leads the psychoactive effects of cannabis, while CBD (cannabidiol) offers beneficial properties. In addition to THC, growers and processing labs often prioritize tetrahydrocannabinolic acid (THC-A), the natural precursor to THC that is easily converted by decarboxylation during drying and/or heating of cannabis. A quick and simple method to determine the levels of THC and THC-A in a cannabis sample is of great interest.

The most prominent cannabinoids present in cannabis are:

  • Acid cannabinoids: CBDA, CBGA and THCA.
  • Neutral cannabinoids: CBD, CBG, THC and CBN.

Medical cannabis usually exhibits higher concentrations of CBD and lower concentrations of THC, compared to recreational marijuana, which has a more significant presence of THC. The THC/CBD ratio is crucial for medicinal cannabis. For example, medical cannabis might feature 20% CBD and 1% THC, while recreational cannabis might have a typical composition of 25% THC and 2% CBD.

If we analyze a cannabis extract from a plant previously tested for pesticides, fungi and molds, it will not be necessary to repeat these studies. However, it will be imperative to determine the potency of CBD and THC.

Types of cannabis analysis

Cannabis analysis plays a critical role in ensuring the purity and quality of products, especially in the context of medicinal cannabis. These tests are crucial to verify the precise levels of cannabinoids, such as CBD, recognized for its therapeutic properties.

By evaluating the presence of unwanted substances, such as pesticides and heavy metals, it is ensured that medicinal cannabis is safe for consumption by patients. These analyzes not only support the integrity of the products, but also provide doctors and patients with reliable information on the chemical composition, allowing precise selection of treatments based on specific cannabinoids and ensuring the effectiveness and safety of medicinal cannabis. There are quantitative and qualitative measures:

Quantitative tests

As the name suggests, quantitative tests provide the quantity of what is being analyzed, actually measuring the amount of the substance being analyzed within the sample. For example, potency tests for cannabis give you an actual number for the presence of THC.

Qualitative evidence

In contrast, qualitative tests do not indicate how much of what is being tested is present in the sample, they only indicate whether it is present or not. These tests are usually used for descriptive purposes. For example, a test for a certain bacteria may indicate whether it is detected, but does not provide any measurement.


Quantitative measurements are often used in qualitative reports to describe the presence of an analyte (something being analyzed). For example, if the quantitative measurement of an analyte is 5 to 10 units, it would be described qualitatively as a medium density. Thus, a measurement of 7 would be used to describe the qualitative density of the analyte.

5 key elements of cannabis analysis

Safety and quality play a crucial role in the process of ensuring products that meet the highest standards. Cannabis analyzes focus on five key elements, highlighting their importance in public health and ensuring product quality.


Safety analysis ensures that the product is safe to both handle and consume. Composition testing is included to identify any potentially harmful substances in the cannabis flower.


Ensure that the contents of the package match the label, guaranteeing the absence of contaminants. It is crucial for cannabis flowers and edibles.


Related to product potency, strength testing includes cannabinoid analysis to ensure the concentration is accurate.


Ensures the absence of chemical or microbial contaminants, including heavy metals, pesticides and other common contaminants.

Calidad en el análisis de cannabis

Quality is supported by the four elements above, ensuring good cannabis analysis. In conclusion, cannabis analysis plays an essential role in providing detailed information on the chemical composition, potency and purity of the products,


These tests not only protect consumers by improving public health, but also ensure compliance with regulations and increase customer confidence in a market where transparency is essential. The variability in results highlights the need for uniform standards and protocols in the cannabis industry.

Ultimately, cannabis analytics drives continuous improvement in medical cannabis and production, promoting a responsible and trustworthy industry.
