Some CBD brands take shortcuts in manufacturing products which can have a harmful effect on consumers. These products sometimes contain pesticides, heavy metals and other contaminants. To be sure of the quality of the product you purchase, it is important to make sure that the product being purchased comes with independent lab test reports. Third party testing is a requirement. Chow420 makes this easier for you by supplying each listed product lab results detailing cannabinoid, terpenes and flavonoid content. Contaminants are also checked for and any products with levels above standard thresholds are rejected. Learn more about our Know What You Buy program.
