Mycotoxins are toxic compounds produced by certain types of fungi that can contaminate various agricultural products, including cannabis. These fungi, such as Aspergillus, Penicillium, and Fusarium species, can grow on cannabis plants under certain environmental conditions, particularly when there is high humidity, poor air circulation, or improper storage conditions.

When cannabis plants are exposed to these fungi, they may produce mycotoxins as a defense mechanism. These mycotoxins can be present on the plant material, such as the flowers and leaves, as well as in cannabis-derived products such as concentrates, oils, or edibles. Mycotoxin contamination in cannabis can occur at any stage, from cultivation and processing to storage and distribution.

The most common mycotoxins associated with cannabis include aflatoxins, ochratoxin A, and fumonisins, among others. These mycotoxins are known to have harmful effects on human health and can cause various issues such as liver damage, respiratory problems, immune system suppression, and even carcinogenic effects.

Due to the potential health risks associated with mycotoxin exposure, regulatory bodies and industry standards often impose limits on acceptable levels of mycotoxins in cannabis products. Testing for mycotoxins is crucial for cannabis manufacturers to ensure the safety and quality of their products, protecting consumers from potential harm and complying with regulatory requirements.
