What Does ‘Lab Tested’ Mean on Cannabis Products?
‘Lab tested’ is the most important two words on any package – and also one of the most misused. Here is what real testing covers.
The standard panel
- Potency: actual THC/CBD percentages vs the label
- Pesticides: screening for agricultural chemicals
- Heavy metals: lead, arsenic, cadmium, mercury from soil and hardware
- Microbials: mould, yeast, E. coli, salmonella
- Residual solvents: leftovers from extraction
How to verify the claim
Look for a batch number matching a certificate of analysis (COA) from an independent, accredited lab – not an in-house one. Reputable sellers publish COAs per batch and will quote the batch code on request.
Quick answers
Is lab tested the same as legal?
No – testing is a quality step; legality depends on your jurisdiction.
Can small brands afford real testing?
Yes – per-batch panels are routine costs for serious producers; absence of a COA is a choice, not a budget issue.
