Terpenes, the aromatic molecules found in plant resins, are responsible for the variety of flavors and odors in cannabis flowers and extracts. Terpenes also contribute to some of the medical and physiological benefits of cannabis. We test cannabis and hemp for 42 different terpenes, including Eucalyptol, Linalool, and Borneol. Learn more about terpenes.

It is the method for ensuring a product is homogeneous at the start of sampling, continuing through the testing process. This is important in ensuring that the process used to manufacture edible products and other cannabis goods produces uniformity and consistency.

Yes, residual solvents need to be tested for. Solvents are organic volatile chemicals that are used in the manufacturing or extraction process. In cannabis, they are used to extract cannabinoids or terpenes from the plant material. These solvents are often not completely removed by practical manufacturing or extraction processes. Learn about residual solvents.
