The shelf life of hash oil depends on several factors, such as the quality of the oil, how it was extracted, and how it's stored. Generally, if it's stored in an airtight container in a cool, dark place such as a fridge, it can last for several months to a year. However, the potency and flavor may degrade over time. It's best to check the manufacturer's recommendations and use your senses to determine if the oil is still good to consume. If it looks, smells, or tastes off, it's better to dispose of it and get a fresh supply.
