Synonyms: Toxic metals, Trace metals | Category: Lab Testing & QA/QC
Key takeaways:
- Heavy metals can contaminate cannabis during cultivation or processing.
- Common heavy metals include lead, mercury, arsenic, and cadmium.
- Testing for heavy metals ensures product safety and consumer health.
- High levels of heavy metals can cause health risks if ingested or inhaled.
What it is / How it shows up:
Heavy metals often appear in Certificates of Analysis (CoAs) provided with cannabis products to ensure safety and compliance. They are naturally occurring elements that can be absorbed by cannabis plants from the soil, water, or air. Common heavy metals of concern are lead, mercury, arsenic, and cadmium. These elements can be harmful if present in high amounts, potentially causing health issues over time. Their presence in cannabis products is strictly regulated to protect consumers.
How it’s measured or identified:
- Inductively Coupled Plasma Mass Spectrometry (offset-4 transition-colors hover:underline" title="Learn more about ICP-MS">ICP-MS)
- Atomic Absorption Spectrometry (AAS)
- Testing performed by certified laboratories
Use in context:
- "The product's CoA showed no detectable levels of heavy metals."
- "Regulations limit the concentration of heavy metals in cannabis products."
- "Heavy metals testing is crucial for consumer safety."
Safety & compliance in Canada:
- Health Canada sets strict limits for heavy metals in cannabis products.
- Regular testing is required to ensure compliance with safety standards.
