Even if the package is not opened, the packaging process of 10 years ago should be wet. Even if it doesn't appear on the surface, it's not easy to take it out and light a cigarette. Even if it is lit, it will not smoke (that is, cigarettes are difficult to burn). If it is difficult to smoke, it will smell moldy. You can't find the taste of tobacco leaves in those years at all. I can't feel nostalgia at all, and I can't find the feeling of those years. So, put it away until it becomes an antique and is collected _!
As a smoker, in essence, this cigarette will not produce harmful substances other than the original cigarette for a long time. This is basically safe. After all, he is just tobacco or tobacco wrapped in tobacco. The ingredients here can't let them interact to produce more harmful substances, and people will have unpredictable and serious consequences when they touch them. This doesn't exist.
Finally, if you think this kind of cigarette takes up space, you can take it away and throw it away. If you think it won't affect your living space, you can leave. However, if you really want to know whether you can smoke, you can know the result by lighting one yourself. After all, we can only give you some advice through some experience and intuitive judgment, and these suggestions are more just guesses than facts.
It is also the wisdom of a great leader. Practice is the only criterion for testing truth. There are all kinds of conjectures and possibilities. Why not pick up one, light it with that curious flame, taste it and get to know it again?
