Highly toxic nonliving compounds that are a byproduct of fungus production during cultivation and known to be dangerous to humans, animals, and plants. Jurisdictions with regulated medical or adult-use cannabis tend to require analytical laboratory testing of the two most common mycotoxins found in cannabis, aflatoxins, and ochratoxins. Laboratories report the quantities of mycotoxins detected in micrograms per kilograms (µg/kg).

Cultivators can reduce the mycotoxins in their crops by using good agricultural practices and implementing control measures throughout the harvest stages.  

This preroll is safe to smoke because it does not contain any mycotoxins.
