Cannabis growing and the processing required for its transformation into inhalable, edible, and absorbable products makes these consumer goods inherently susceptible to dose inconsistency and contamination by, for example, extraction solvents, growth promoters, and pesticides.

Key challenges in this marketplace include the lack of consensus on pesticide use and the analytical testing of cannabis products to ensure their safety.  The trend towards increasing concentrations of tetrahydrocannabinol (THC) and other active compounds in products also raises issues of potential health risks.  Moreover, the presence of pesticides and other chemicals in cannabis products raises concerns regarding California’s Proposition 65.
