Testing laboratories

Testing laboratories make sure cannabis goods are safe for consumption.

Required testing

Testing labs test cannabis goods for:

• Cannabinoids and terpenes

• Residual solvents and processing chemicals

• Residual pesticides

• Heavy metals

• Microbial impurities

• Mycotoxins

• Moisture content and water activity

• Foreign material

Reporting test results

Testing labs report results on a Certificate of Analysis (COA). The COA says whether the batch passes or fails testing for each substance.

Labs can only issue COAs and results after they finish all tests. Labs cannot change them after they’re issued without permission.

Sending results

Within one day of finishing a batch’s testing, the testing lab must:

• Upload the COA to the track and trace system

Cannabis goods that fail testing

Batches of cannabis goods that fail testing can only be:

• Destroyed by the distributor

• Remediated by a manufacturer

Remediation removes contaminants from a product. Only manufacturers can remediate a product.

Reliability of test results

Testing laboratories must:

• Become ISO accredited

• Use standard operating procedures

• Develop a laboratory quality assurance program

• Participate in a proficiency testing program

ISO accreditation

Cannabis testing labs in some states must maintain to ISO/IEC 17025 accreditation. ISO accreditation is a measure of quality used by universities and research centers worldwide. This standard, established by experts, requires labs to show:

• Technical competency

• Reliability of test results
