In addition, the cannabis manufacturing process can itself increase the concentration of heavy metals, raising the risk of heavy metal toxicity still further. Cannabis extracts, for example, may have a dangerous concentration of metals. These factors together mean that testing for heavy metals in cannabis is an absolute necessity.
Cannabis Heavy Metal Testing Requirements
The state of California regulates the testing of four specific heavy metals in cannabis plants. Cannabis heavy metal testing in California must test for levels of arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg). This testing is for the purpose of keeping consumers safe.
Following these regulations is also, of course, a matter of law. California’s Department of Cannabis Control performs investigations and routine inspections to ensure compliance with state law. Violations are taken seriously, so getting the proper testing done is vital.
