Long-term smoking is not recommended, because even if it is not moldy, smoking tastes worse. Generally speaking, once cigarettes are stored for more than two years, the taste will definitely change and the quality will be greatly reduced.

A good environment for preserving cigarettes is to control the temperature at about 4 degrees Celsius and the humidity at 60%. If you don't smoke for a while, don't open the package. You can wrap the whole cigarette with plastic wrap and put it in a plastic bag for storage in the freezer.
