Your code should return a stored string if you have setItem earlier or null if you didn't. I don't know why the need for JSON.parse. How about this:

async getUser() {
    let user = null;
    AsyncStorage.getItem("CURRENT_USER")
    .then((result) => {
        if (result !== null) {
            user = result;
        }
    });
    return user;
}
