Where do they get the Tobacco?

I’ve been wondering, where is everyone on BSG getting their cigarettes and cigars? You can make a still and produce your own alcohol, but tobacco? I assume a lot of them were lying around from before the Cylon attack on the colonies, and perhaps people in the fleet were carrying loads of them to sell. Or maybe one of the fleet’s ships, similar to the botanical cruiser we saw in the miniseries, grows the plant. But if they’re producing their own agriculture on ships, wouldn’t they want to eliminate non-food items as much as possible because of the limited space?

Then again, the colonial fleet is immune to neither addiction nor commercial motives, so I suppose there could be a lot of unseen factors. So, when the last stogie from the colonies has been smoked, what will happen? They say a civilization is only three stogies away from revolution…or something like that. Maybe a shortage of tobacco will be just the thing to kick off the Resistance large-scale.

Update: In the episode “Black Market,” we do see people trading cigarettes and cigars in bulk, so it appears at least one of the ships in the fleet may have had a ton of them in storage already.
