You are probably right on added chemicals
Where I live it is hard to buy tobacco directly from farmers , so little option to get other kind of tobacco , anyway it is overtaxed
Coca-Cols ,RedBull, quimically growned vegetables , we are eating and drinking many new things this century , Do know the long term effects?
Looks like tobacco have been smoked for at least 15k years , probably there are reasons for that
People can be addicted to so many things...

Addictions are not good ?
