It’s also a good idea to be aware of what extraction process was used to make the product. Many cannabis experts agree that the CO2 method is best for producing premium oil that stays potent longer because the hemp or cannabis compounds remain stable during this type of extraction. Other methods may destabilize the compounds, potentially creating a lower-quality bottle of CBD oil with a shorter shelf life.
A bottle of high-quality CBD oil can be expensive, and if you’re like us, you want to make that liquid gold last as long as possible. If you’re only using a few drops a day, it could be many months or even a year before you use up the entire bottle. Which might leave you asking yourself, “Does CBD oil expire?”
Does CBD oil go bad?
The aroma and flavor of CBD oil may become unpleasant over time, transforming from earthy to skunky. You can also observe visual changes in the oil, which may turn cloudy over time. Likewise, the texture of CBD oil will change and the oil may appear thicker and lose its smooth consistency. Lastly, a change in color indicates that the CBD oil is no longer fresh.

How long does CBD oil last?
CBD oil does not spoil or turn rancid like milk or other oils, so you are unlikely to become ill if you consume a small amount of the product past its prime. This is especially true if you are microdosing. But to be on the safe side, toss any bottles that have been improperly stored or sitting in your medicine cabinet for longer than two years.
One additional way to protect your CBD oil from light is to wrap the dropper bottle with aluminum foil. However, most CBD oils already come in dark-colored, airtight bottles.
Factors such as dosage and frequency of use also dictate when a CBD product expires. In addition, while some infusions and extracts may experience degradation in a short period, others may stay fresh and usable indefinitely.
The most common way to extract CBD includes the use of naturally-occurring CO2. This extraction method is believed to produce the cleanest, highest quality product, containing cannabinoids, flavonoids, phytochemicals, and terpenes.
Store Your CBD Oil Away from Light and Heat
Storing CBD oils correctly can result in longer shelf life. Proper storage can discourage the degradation of oils and the proliferation of other chemicals that can destroy the compound.
Most methods of extraction and bottling processes take the heat and air exposure into account when trying to maximize the effectiveness of the oil once sold to customers. Without these protections in place, you would be consuming low-quality CBD oils.
The Impact of Extraction Method on CBD Oil Shelf Life
Overall, the fridge is a good option if you seldom use CBD and want it to last over a year. Otherwise, your pantry works well as long as you seal the container after each use.
While CBD extraction methods aren’t standardized, there are some pros and cons to each technique. Many of these techniques may significantly impact CBD’s shelf life.
