unless one lives in the regions that tobacco companies are growing, it may be not worth the effort as it needs a specific environment/climate to succeed.
Back in the late 70's, a Canadian tobacco bought land in the Kelowna region which really baffled and worried the local farmers as to why they would do this, as you can't grow decent tobacco in the dry conditions of that region.
They tried to dodge the concerns of the farmer but eventually stated they bought the land just in case marijuana ever becomes legal to grow

They made it legal to grow tobacco in Canada about 25 years ago, but I don't know anybody who has tried....just like MJ, there is a drying process that is critical for a proper finish
