Proof, not promises
Lab results.
Every batch we sell is tested by an independent, ISO-accredited lab. Product pages link directly to the batch certificate of analysis (COA), and the batch number printed on your package matches the report.
What we test for
- Potency: the cannabinoid profile and total THC listed on the batch report.
- Pesticides: a broad panel based on state cannabis testing requirements.
- Heavy metals: lead, arsenic, cadmium, and mercury.
- Residual solvents: the solvents used in extraction.
- Microbiology: mold, yeast, and harmful bacteria where applicable.
How to read a COA
Start with the batch number and product name to confirm the report matches your package. Then check the total THC result and the “pass/fail” columns for pesticides, heavy metals, and solvents. A report should have a lab name, accreditation number, and a date. If any of that is missing, ask us for a new report.
Find your batch
The fastest way is the COA link on your product page. If you already have the package, email contact@mainstreetsmokeshop.com with the batch number and product name, and we'll send the PDF within one business day.
