Stability Studies

As licensed producers, your utmost priority is the safety and effectiveness of your product for patients and consumers.

Cannabis products with accurate expiration dates are essential for providing consumer assurance that the product is high quality, contains the potency or cannabinoid/terpene profile as per the label claim, and is safe to consume.

What is a stability study?

A stability study is an examination of a substance or product over a specified period of time to examine the effects of different storage conditions on the characteristics of this substance or product. This test essentially identifies the product or substance’s expiration date.
