Why is there no nicotine free tobacco on the market?

The burnable leaf would have to survive the extraction process (and I cannot imagine this happening, or think of an analogous process from which a comparable mateiral to shreded tobacco leaf comes out the other end), or alternately someone would have to find/breed/engineer one without nicotinoids in it (and that’s a lot of work)? That’s what i can come up with for why not. Impractical.
