For all plants available, why tobacco?
"Tobacco is the easiest land plant in which to manipulate Rubisco and so serves as the test case for developing a more efficient Rubisco that can be transferred to more agronomically relevant species, Gunn said."
Call it Nicotiana instead!
I've tried curing and smoking the leaves, but without the right facilities it doesn't go too well and doesn't produce anything close to the quality of store bought pipe tobacco.
I never did try to smoke a garden grown nicotiana. Thinking back on it, I probably should have grown my own and really got to grips with it. When I gave up fags, they costed around £10.50 for a packet of 20 Lambert and Butler. Nowadays £11.95 (1)

No pressure, but I do recommend not having to gasp for breath when you walk up a hill. It is a bit of a pain. To be fair, I'm not in the best of shape but my lungs are not what they were.
