Precautions:
You can ask to check the production date when you buy cigarettes. If it takes too long, you should buy it carefully, because cigarettes will also expire. The environment in China is very different, and the shelf life depends on the local climate change and the environment where cigarettes are stored.
In a cool, ventilated and dry environment, unpackaged cigarettes can be kept for one or two years. Some old smokers like to collect old fires, wrap cigarettes in plastic wrap and put them in the refrigerator, and even buy professional tobacco protection boxes. In this environment, cigarettes will not expire for five to ten years.
