Where could I purchase a non-tobacco non-nicotine chew?

[EricaMuterspaw]

I am looking for a non-tobacco and non-nicotine chew and was wondering if I could buy it at a gas station or store? And can you buy this if you are under 18?
There is some type of chew that is made from tea leaves and other herbs of that type.

Chew has tobacco no matter what.
But they sell "shredded beed jerkey" which they put in cans like skoal that you can buy at any age because its beef jerkey.
