Even in California? I'd think that they'd have something worse than the rest of the country as far as growing laws are concerned.
I may be wrong, but for some reason I believe the tobacco growing laws are federal and can not be superceded by the states.
Here in Los Angeles they'll probably just mosey on by and spray the crops as part of their mosquito abatement program.
Then they'll sue you for growing your own claiming you were attempting to evade taxes by not purchasing the cigs in a retail outlet. :^)
