Cannabis product testing

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

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[edit]

Colorado[edit]

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 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[edit]

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

Standards[edit]

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]
