Ordinary cigarettes shall not be stored for more than two years. Cigarettes are very complicated products, and the storage time varies greatly due to different storage environments.

Cigarettes of the same brand may have different shelf life in southern and northern China. For example, in the south with high temperature and humidity, after only one summer, dry cigarettes are alcoholized and absorb enough water, and it is easy to get moldy when changed in the morning; In the dry and cold north, the shelf life of cigarettes can be as long as several years.

Cigarettes can be stored for two years if stored correctly in a dry environment. Cigarettes usually need to be aged in the warehouse for about 10 days after leaving the factory, then enter the market and finally reach consumers through dealers. It is almost impossible for truly popular brand cigarettes to stay in the hands of dealers for a year or two. Most moldy cigarettes are caused by improper storage in the hands of consumers.

The best environment for preserving cigarettes is to control the temperature at about 4 degrees Celsius and the humidity at 60%, because even if cigarettes are not moldy and deteriorated, their taste will change and their quality will be greatly reduced.
