How long is the shelf life of cigarettes and why?

The shelf life of cigarettes varies with different storage environments.

A dry environment can be preserved for two to three years, but if the environment is not good, it can't be preserved for even one year.

The same brand of cigarettes has different shelf life due to different temperature and humidity in different places. For example, in places with high temperature and humidity, after only one summer, dry cigarettes are alcoholized and absorb enough water, and it is easy to become moldy when changed in the morning; In dry and cold areas, the shelf life of cigarettes is as long as several years. Wrap cigarettes in plastic wrap and put them in a refrigerator or a professional tobacco protection box. In this environment, cigarettes will not expire for five to ten years.

Note that it is the cold storage area of the refrigerator, not the frozen area. Because if placed in the freezing area, cigarettes will freeze, dehydrate and harden, and the original balance will be destroyed due to the loss of water, which will affect the quality and taste.
