There are currently no state or national testing mandates for Fusasrium toxins in cannabis, and regulations vary greatly for Aspergillus toxins. To better understand the effects of these fungi and their toxins on human health and disease, I assembled a research team of plant pathologists and toxicologists to conduct a review of the scientific literature on fungal contaminants in cannabis.
