A recent review published in Frontiers in Microbiology examined the risk of fungi and other pathogens potentially contaminating cannabis. The research team analyzed data and international and domestic regulations related to the cannabis and hemp industry. They also focused on several pathogens that produce mycotoxins that can negatively impact humans.
The researchers studied Mucor, Aspergillus, Penicillium, Fusarium, and other fungi that can damage cannabis plants and produce mycotoxins. Fusarium mycotoxins are currently unregulated, even though they can cause moderate to severe vomiting. Environmental factors such as the cultivation site conditions, soil or soilless media use, and other plant care methods can contribute to potential contamination.
The researchers reviewed studies that indicate some fungi may produce infection in lung and skin tissues. The study revealed that smoking was the most common cause of this health effect. Adverse effects also happen when tainted edibles are consumed, but smoking increases the likelihood of infection.
The study indicated that patients with cancer, HIV, and type 1 diabetes were most susceptible to infection. Therefore, the researchers recommended that immunocompromised individuals take extra precautions and only use sterilized cannabis products. In addition, they suggested implementing a two-tier system that identifies products intended for medical and recreational use. More thorough quality control will provide better protection to medical cannabis consumers. The review also highlighted some potential risks for those workers harvesting cannabis plants.
The lack of data on contaminant presence and policy variations across states have hindered product safety research and the development of regulations that protect all consumers.
The article also examined the management of the possible toxins before harvest and after harvest. The researchers recommended increased research on agricultural practices, regulatory matters, and mycotoxins present in cannabis products to align production-related issues and human safety issues better.
