Keeping your vape safe is important to maintain the potency of cannabinoids. To do so, it’s best that you keep them out of sunlight and dark places like a refrigerator or cabinet where they will last longer than if exposed directly on room temperature surfaces for an extended period time frame before losing effectiveness due too degradation caused by air exposure over long periods as well as light-induced chemical processes such because photolysis which leads directly into photodegradation resulting in color change ( earliest evidenced by yellowing), structural breakdown etc.. The storage environment should be cool but not fridge cold!
