Heavy metals are toxic elements that can accumulate in cannabis plants from contaminated soil, water, or fertilizers. These metals pose serious health risks because they bioaccumulate in the body over time, causing neurological damage, organ toxicity, and developmental problems.
Our laboratory tests for four heavy metals of primary concern in cannabis products:
Minnesota establishes stricter limits for inhalable products compared to edibles, reflecting the increased bioavailability and health risks associated with inhaled contaminants. Our testing uses inductively coupled plasma mass spectrometry (ICP-MS) to detect these elements at extremely low concentrations.
Vaporizer hardware components may leach heavy metals into cannabis oil during use. Finished vape products should be tested for heavy metals even if the concentrate itself passed testing.
