What a testing license allows
Testing laboratory licenses let independent labs test cannabis for potency, pesticides, heavy metals, microbials, residual solvents and other contaminants before products can be sold.
Typical requirements
- ISO/IEC 17025 accreditation (or a path to it within a set time)
- Independence: owners usually cannot hold any other cannabis license
- Qualified scientific staff and validated testing methods
- Laboratory-grade facility and equipment
Typical steps
- Plan your lab and testing methods to state standards.
- Begin the accreditation process.
- Apply for the state license and pass inspection and proficiency testing.
