Requirements for Marijuana Testing Labs in Maryland

It is mandatory for independent testing laboratories to have International Organization for Standardization or ISO-17025 accreditation.

ISO-17025 is the standard for testing and calibration that most countries, including the United States, use to accredit laboratories.
