The widespread distribution of the Aspergilli in nature has resulted in the vulnerability of many agricultural commodities to possible contamination with potentially toxin-producing species. Poor handling practices during the illicit processing and storage of marihuana plant material increase the likelihood of contamination with low levels of secondary fungal metabolites, mycotoxins, which have been shown to have deleterious effects in both animals and humans (Busby and Wogan, 1984; Dvorackova et al., 1981; Dvorackova, 1976; IARC, 1976; Newberne and Butler, 1969).
