Cannabidiol (CBD) is a popular natural compound derived from the cannabis plant. However, during the extraction process, impurities can be introduced into the final product. These impurities can include residual solvents, pesticides, heavy metals, and microbial contaminants. It is important for CBD manufacturers to test their products for impurities to ensure their safety and efficacy. Consumers should also be aware of the potential risks associated with consuming CBD products that contain impurities.
