ANAB provides accreditation for laboratories that perform analytical testing of cannabis and cannabis-derived products, including oils, edibles, drinks, concentrates, flowers, butters, and waxes, and hemp and products derived from hemp. Testing of cannabis products is necessary to demonstrate that they are safe for consumption and free from harmful levels of contaminants.

Video: Accreditation Manager Matt Sica describes the five-step accreditation process and discusses how to prepare for a successful outcome, the documents labs are required to submit for accreditation, and the main challenges cannabis labs face.

ANAB accredits cannabis testing laboratories to ISO/IEC 17025 for a variety of relevant tests, including:

  • Cannabinoid testing and content (e.g., THC, THCV, CBD, CBDV, CBG, CBC, and CBN)
  • Terpene profile 
  • Pesticides 
  • Microbiological contaminants  such as mold, and bacteria
  • Heavy metals
  • Residual solvents

Demand for testing laboratories is growing as many states have legalized medical and adult-use recreational marijuana. ANAB can accredit your lab to meet state regulatory requirements.

ANAB's cannabis testing laboratory accreditation program provides independent, third-party accreditation assessments serving both the medical cannabis and adult-use recreational markets. The program uses ISO/IEC 17025 as the base standard along with any relevant state regulatory requirements.
