Welcome to the board from northwest Louisiana.

I did a little bit of looking, because to be honest with you, I'm kind of interested as well. I'm not really in a position to do this now, but would at least like to read about it.

It looks like your best bet would be to grow your own tobacco. Another member on this board that is growing his first batch (search is your friend), and I'm interested.

On resource is here, another is here, and yet another is here. My guess is that you'd need a relatively stable warm climate, time, and no tomato plants nearby. Then you need more time to allow for fermentation. I've actually ordered some seeds (the wife did, actually), but they haven't come in yet. I plan on posting regularly my growing adventures.

Good luck, and let us know what you come up with.
