If the weather where your at is hot and humid, not a very long time, maybe a week at most.
BUT, if you put it in the fridge, it can last for weeks.
I don't chew, but I dip, and if I find myself with a dry can, I put a little bit of water on it (one drop at first, and work up, because you don't want tobacco that is dripping with water) and then its fine. I don't know if this would work with chew or not, but I guess if its extremely dry to the point where you are just going to get rid of it, then it would be worth a try.
as long as it dosent smell funny or get dry, and if it gets dry just put a little rum in it

Yes, Chewing Tobacco is very bad for you're jaws. Chewing Tobacco has little pieces of glass or sharp wood chips in it. Once you put Chewing tobacco in you're mouth the glass or wood chips make cuts in your gums and the nicotine inside flows into you're blood. Chewing Tobacco can be very bad for your jaws and everyone should stay away from it. Although, chewing tobacco does treat everyone different, you never know you're consequences, so if I were you, I would stay away from Chewing Tobacco.
it can stay fresh for 2 weeks
Forever
It will stay fresh for some hours. Not too long. So it depends how long the fridge been off. Too long is bad.
cod will stay fresh forever if you freeze it in a air tight bag.
i would say brownies stay fresh for about 3-5 days if they are in a sealed container.
I tried both dipping and chewing tobacco. Chewing tobacco is much milder; it is not shredded, so has less surface area to release nicotine and oils. This allows for a longer and milder soak. Dipping tobacco, which comes in a can, is shredded; thus, most of the oils are already on the surface of the tobacco, which creates an instant hit of nicotine and oils. If you chew often throughout the today to stay awake as I do, then use chew; it will be less harsh on your mouth and stomach.
Weed stays fresh for a long time. You can put it in a plastic bag to keep it fresh for a long time or you can also freeze it.
Not that long, About 30mins to an hour at the most.
two days
i don't think it will help the lifespan of the flowers
