I am wanting to start marketing something as a "cigarette detox pill,"...... it is a mixture of various herbs that have been shown to remove certain toxins and heavy metals found in cigarette smoke.....

I don't expect it to be approved by the FDA, nor does it need to be. I was just in Wal-Mart and 90% of their vitamin shelf was non-FDA approved.

Is there anything I'm not thinking of? Any state licensing, etc.?

None of the components are controlled substances, or anything even close.
