ok so i have about 8 Camel snus cans i got about 3 years ago to help me stop smoking. although since i don't do dip or snus. i decided just to put it in a zip lock bag take all the air out of the bad and seal it up tight. and put it in a door in my coffee table. so the expiration date is in 09. but they're unopened and was in room tempature. i just took them out today thinking i might try one and i needed to know what i should do about them. any help?
