.my buddie just swallowed some of her dads tobacco.....?

It says 32ounce. And she was hungry, and didn't know what it was. Her dad is always eating it and she thought it was her dads candy. Shes also also a little mentally retarded. By that I mean, she has a mild case of down syndrome. Is this unhealthy? If she swallowed the whole thing in the can?Is she going to be okay? Is this illegal? Is tabocco illegal.
