Cannabis product testing

Cannabis product testing is product testing of the properties of cannabis destined for consumer use. Analytical chemistry and microbiology laboratories determine cannabinoids, water content, heavy metals, pesticides,[1] terpenes, yeast, mold and mycotoxins, and solvents.[2][3] These laboratories came about when advocates of cannabis testing brought up concerns with potential contaminants.[4][5][6]

History

Colorado

In 2015, the first government standards for testing were proposed in Colorado's legislature, when potency and microbial testing became mandatory in the state.[7][8][9] Colorado cannabis testing laboratories, such as AgriScience Labs, are regulated by the Colorado Department of Revenue's Marijuana Enforcement Division and the Colorado Department of Public Health and Environment.[10] Over the next several years, other tests became mandatory, such as residual solvent analysis and pesticides.[10][11]

Other states

Cannabis testing is also required in other states, such as California,[12] Oregon,[13] Massachusetts,[14] and Nevada.[15]

Standards

Calls have been made to unify cannabis industry standards with existing testing organizations such as ASTM International (ASTM D37)[16] or International Standards Organization (ISO/IEC 17025).[17]
