I am smoking GMO corn silk in my cob. It's rather harsh on the back of my throat though. And I miss the nicotine, so I have added some flake dried red pepper which contains nicotine. Wow! What a flavor boast. Since this mixture is tax free. The costs of our hobby goes down. Another plus is that your other half will soon beg you to go back to smoking tobacco in the house. Maybe all of us will be smoking corn silk in a few years.
