How Long Does Cannabis Oil Last Unopened?

Jun. 21, 2023

Cannabis oil, also known as CBD oil or hemp oil, is a popular product derived from the cannabis plant. It is known for its potential health benefits and therapeutic properties. Proper storage and handling of cannabis oil are crucial to maintain its quality and potency. If stored correctly, unopened cannabis oil can have a relatively long shelf life. In this article, we will explore the factors that affect the shelf life of unopened cannabis oil and provide general guidelines for storage.


The packaging of cannabis oil plays a vital role in preserving its freshness and potency. Look for oil that comes in a dark-colored, airtight container, such as amber glass bottles or opaque plastic containers. This type of packaging helps protect the oil from light exposure, which can degrade its quality over time.

Extraction Method:

The extraction method used to obtain the cannabis oil can impact its shelf life. CO2 extraction is considered one of the best methods, as it preserves the cannabinoids and terpenes effectively. Other extraction methods, such as solvent-based extraction, may introduce impurities or residues that can affect the oil's stability and longevity.

Quality of Ingredients:

The quality of the cannabis plant and other ingredients used in the oil can affect its shelf life. Ensure that you purchase cannabis oil from reputable brands that source their ingredients from reliable and trusted suppliers. High-quality ingredients are less likely to degrade or spoil quickly.

Storage Conditions:

Proper storage is crucial to extend the shelf life of unopened cannabis oil. Here are some important factors to consider:

  • Temperature: Store cannabis oil in a cool, dark place away from direct sunlight and heat sources. Excessive heat can degrade the cannabinoids and other compounds in the oil, reducing its potency. Aim for a temperature range of 15-25°C (59-77°F).

  • Humidity: Moisture can promote the growth of mold and bacteria, which can spoil the oil. Keep the oil in a dry environment with humidity levels below 60%.

  • Air Exposure: Oxygen exposure can lead to oxidation and degradation of the oil. Ensure that the container is tightly sealed to prevent air from entering. Oxygen absorbers or vacuum-sealed packaging can help further reduce oxygen exposure.

Shelf Life:

The shelf life of unopened cannabis oil can vary depending on several factors, including the extraction method, quality of ingredients, and storage conditions. Generally, unopened cannabis oil can last anywhere from 1 to 2 years or even longer if stored properly. However, it is important to note that the oil's potency may gradually decrease over time, especially for oils that are rich in cannabinoids like THC and CBD.

Check for Signs of Spoilage:

Before using unopened cannabis oil, it is important to inspect it for any signs of spoilage or degradation. If the oil has an off odor, unusual color, or has developed mold, it is best to discard it. Consuming spoiled oil can lead to potential health risks.

Use-By Date:

Some reputable manufacturers may provide a use-by or expiration date on the packaging. This date indicates the estimated period during which the oil is expected to maintain its quality and potency if stored properly. It is advisable to follow this date as a guideline.


Proper storage is key to maintaining the quality and potency of unopened cannabis oil. By ensuring that it is stored in a cool, dark place away from heat, light, and moisture, you can extend its shelf life. While unopened cannabis oil can last 1 to 2 years or longer, it is essential to check for signs of spoilage and follow any use-by dates provided by the manufacturer.
