Microbial testing for cannabis products is a crucial quality control measure used to assess the safety and purity of the products. Cannabis is susceptible to fungi and bacterial diseases as its growing conditions are often ideal environments for microbial growth. Microbial testing involves the analysis of samples to identify and quantify microorganisms, such as bacteria, fungi, and molds, that may be present in the cannabis plant or its derivatives.

Instruments Used

Samples are analyzed using qPCR.

Product Test/Sample Sizes Needed (full microbial panel)
  • Flower: 5-6 grams
  • Concentrate or extract: 5-6 grams
  • Infused products: 5-6 grams

Heavy Metals

Cannabis plants and cannabis-infused products can be exposed to heavy metals from polluted soil, water, fertilizer, or manufacturing equipment. These hazardous substances can be absorbed and stored in the plants or products, and potentially passed on to patients and consumers. Heavy metal analysis is a critical step in ensuring the safety and quality of cannabis products. By identifying and quantifying heavy metals, you can ensure that your products meet safety standards and provide peace of mind to customers.

Residual Solvents

Chemical solvents are utilized to extract the materials needed to manufacture concentrated cannabis products. These solvents must be purged at the end of the extraction process. Residual solvents testing is utilized to detect and quantify any solvent in a cannabis extract that may be left over from the extraction process. Residual solvents, such as butane or ethanol can be harmful to human health if they are not removed completely. Testing for residual solvents is important to ensure that cannabis products are safe for consumption.

Foreign Matter

Foreign matter testing is a quality control measure used to ensure that cannabis products are free of any foreign materials, such as insects, dirt, hair, or other contaminants. Foreign matter can be introduced into cannabis products at any stage of the growing, harvesting, processing, or packaging process.

This analysis is a microscopic inspection of cannabis and cannabis products for foreign materials.

Instruments Used

Samples are analyzed using a microscope with camera capabilities.

Product Test/Sample Sizes Needed

Moisture Content

The moisture content is the percentage, by weight, that is water in cannabis products. Moisture content is crucial as an indicator of the potential activity of microbiological contaminants such as bacteria and mold. Testing the moisture content of cannabis products can help determine the effectiveness of the curing process.

Moisture content testing is important in cannabis because moisture content can affect the quality, safety, and shelf life of the product.

Instruments Used

Samples are analyzed using a loss on drying moisture analyzer. 

Product Test/Sample Sizes Needed
  • Flower: 1-2 grams

Water Activity

Water activity is a measure of how much water is not chemically bound to a cannabis product. A product’s water activity determines its ability to grow mold or fungus. Microbial growth, including mold and bacteria, is more likely to occur in products with a high water activity.

By measuring the water activity in a cannabis product, it provides an excellent way to analyze how susceptible the product is to microbial contamination.

Instruments Used

Samples are analyzed using a water activity meter. 

Product Test/Sample Sizes Needed
  • Flower: 1-2 grams
  • Infused products: 1-2 grams
