Greece, Greek Chios (Xios) Mastic Gum ( Mastiha or Mastixa ) 100 Gr Box New - Set of 4

Is this gum vegan?

After using it as a chewing gum, can you reuse the same piece for weeks/forever? Is this considered unsanitary/unsafe as it may harbour germs after?

is this product organic?

I was told these could be broken up and put into water or tea to drink... how do I do this as they are chewy?
