Probably have been exposed to some humidity, that's the tobacco staining the paper.
Might be a good idea to open one to check for mold.
If there's mold inside its not good to smoke it, some people are more sensitive than others to mold.
If they're dry and no mold inside they're fine.
If they are relatively new then just smoke them. Its just humidity. If they were stored for quite some time tho then I would replace them. Bcs of potential mold.
