Agreed. I just think it would be thematically appropriate if the tobacco was for the reasons I mentioned previously, along with the negative health effects and tendency for tobacco to soak up nutrients like nobody's business.There's a point where caution becomes paranoia. Not everything in the americas is super cursed.
Compared to the literal tons of definitely, 100% cursed gold entering the european market I don't think people are going to notice if the tobacco makes you more suceptible to seeing ghosts.
As for nobody noticing if it is cursed, fact of the matter is that anything we export will be under increased scrutiny. Side effect of being known as the new Transylvania. Plus, the Dual Monarchies will need our tobacco a hell of a lot less than the Spanish need their New World gold, so there's far less motivation for the authorities to look the other way.
The not-so-native Americans had one as well. It's one of the factors behind Prohibition.Even the British themselves had an alcohol epidemic with the gin craze. So its not limited to native peoples.
