I want to ask you a question. How long can a whole cigarette be kept unopened?

If you can completely wrap cigarettes, make them airtight, and then freeze them in the refrigerator, they can be stored for 3 years without any odor. If it's not wrapped, just put it outside. If the weather is dry, the maximum is 1 year (tobacco is already very dry)! If the air is humid, mildew spots will appear on cigarettes for at most half a year!
