I have a question about what can be bought on Medicaid?

Q) I have a question about what can be bought on Medicaid. I have noticed when I am in line people purchasing items like, bakery cakes and coca colas. I was under the impression that medicaid was for the essentially for survival. I do not consider birthday cakes a existential item. Please inform me about what my tax dollars will cover. I do not have a problem with providing a lone star card for those in need but I do not like to see it abused.
