Do cigarettes have a shelf life?

It has a shelf life, usually about two years.

Cigarettes have a shelf life. Generally speaking, the shelf life of cigarettes is about 2 years, but the specific shelf life is related to the storage environment. If the cigarettes have not been opened, they can be stored in a cool and ventilated place for about 2 years as long as they are kept dry. If the cigarettes are sealed and stored in the refrigerator, the shelf life can be extended to ten years. If the cigarettes are stored in a poor environment, they may become damp and moldy in less than a year. This situation should also be counted as "expired" and cannot be used anymore.

Although cigarettes are a special product, they also have a "best smoking experience period." That is, from the time the cigarette is produced and leaves the factory, how long it takes to smoke it to ensure the best "smoking experience." When domestic regular cigarettes leave the factory, the production date of the cigarette will be marked on the packaging box and the product certificate, but most manufacturers do not specifically indicate this on a carton or box of cigarettes. Generally, there is a printed number on the outer packaging of cigarettes. These are the main anti-counterfeiting passwords of merchants. This printed number contains the production date information of the product.
