Licensed cannabis testing laboratories, sourced from state regulator databases — the labs that run the potency and contaminant panels every batch needs before it can legally be sold.
It is the smallest licence class by a wide margin, which is what makes it useful: a few dozen labs per state is a list you can work end to end rather than sample.

Why This List
Because the class is so small, this is close to every licensed lab in the states we cover rather than a selection of them.
Labs buy analytical instruments, reference standards, consumables and LIMS software — small in number, large in contract value.
Licence filings carry a business phone and email for most labs, so the contact rate is far better than a scraped directory.
FAQ
Licensed labs test each batch for potency and contaminants — pesticides, heavy metals, residual solvents and microbials — before it can be sold. In most states a product cannot reach a shelf without a passing certificate of analysis.
Far fewer than any other licence class — typically a few dozen per state. Most also hold ISO/IEC 17025 accreditation alongside the state cannabis licence.
Every state whose regulator publishes a testing licence class in its public file. Coverage follows the regulators we crawl, so it grows as states are added — the per-state pages show exactly where we have labs today.
