You can grow your own tobacco. Once you do, never buy someone else's (big tobaccos) crops.

It's cheaper, you'll probably smoke a lot less of it (you have to make each harvest last until the next crop is ready!), and you'll have more fun with it when you do (pipe or rolling your own smokes, bragging rights, etc).

I like it that you're keeping it in the nightshade family, shit add some eggplant and you got the trifecta!

Tomatoes are great, especially if you make passata and use your garden waste for canning/pasteurise fuel.
