The COLA Accreditation Program for Cannabis Testing Laboratories is a best practice, quality-oriented program. Cannabis Testing Laboratories providing a wide range of testing services, including testing for potency, terpenes, residual solvents, pesticides, micro-flora and more, are eligible for the program. By earning accreditation through COLA, a laboratory is determined to be in conformance to ISO/IEC 17025:2017, as required by many states.
