To properly store CBD oil products, such as tinctures, salves, balms, edibles or cooking oil, it is recommended to keep the product out of direct sunlight and away from heat or moisture. With this in mind, a dry pantry, cabinet or drawer is a great place to store your CBD. You can also store your CBD oil in the refrigerator, but note that it could change the consistency of the product. If this happens and the oil has trouble coming out of the dropper, run the bottle under warm water and it'll help it dispense like normal. If you are utilizing your CBD products on a daily or regular basis, there is no need to store it in the freezer, but if you have a need for long-term storage, freezing is fine.
In addition to keeping your CBD in a dark, cool environment, air exposure also plays a role in reducing the shelf life of CBD, which is why it is recommended to keep the original packaging when possible. After usage, make sure to tighten the lid or replace the cap. If the product has to be transferred to another container for one reason or another, try to make sure the container is opaque and also as airtight as possible. Always opt to store your infused products in glassware when storing for long-term as well.

Similar to non-infused food products, edible infusions vary in regard to perishability. Chocolate or hard candy will last much longer than pastries or baked goods, but both should be stored similarly to how you would store them if they were not infused with CBD or THC. The same can be said for products that feature common carrier oils. For example, storing CBD products with coconut oil or olive oil should be stored the same way you would store non-infused oils. Products such as butters and cooking oils can also benefit from being frozen, as this will help extend the shelf life.
When it comes to flower specifically, the two worst ways to store the product are on a tray or in a plastic bag, as this increases oxygen and light exposure and will degrade the shelf life. Cultivators follow their own unique methods for drying and curing flower, knowing that moisture and water make a big difference when it comes to maintaining freshness, taste, and potency. As such, many manufacturers dedicated to finding optimal moisture content in their packaging methods and cannabis connoisseurs in general have a lot of nuanced opinions on how to best store flower.
Once you purchase your flower and bring it home, there are several best practices to call upon to keep the product as fresh as possible. Similar to CBD oil products, it is best to keep marijuana or CBD flower in a cool, dark place slightly below room temperature. High temperatures and arid environments will not only dry out the flower, but will also lead to the evaporation of terpenes and the potential development of mold and mildew. Exposure to light will also degrade cannabis. One study found that light is the largest contributor to loss and deterioration of cannabinoids. The study also found "carefully prepared herbal or resin cannabis or extracts are reasonably stable for 1 to 2 years if stored in the dark at room temperature."
It is best to keep flower in an airtight container, and it is best to store it in a container that is comparable in size. In other words, don't store one bud in a jar ten times its size whenever possible. Some will even put an orange peel in their jars to keep the moisture content at an amicable level, although this increases the likelihood of mold. There are even humidity control packs you can purchase that are designed to reintroduce moisture if the conditions become too dehydrated.
Essentially, as a general rule, it is advised to keep an eye on the harvest date on the packaging, as well as go out of your way to avoid exposure to light, extreme temperatures, oxygen, and too much moisture. When CBD and cannabis products are stored properly and with great care, you can extend the shelf-life and make sure your investments aren't going to waste.
