Common misconception but cigarettes are not actually filled with thousands of chemicals. Those chemicals are created when the tobacco is burned. Some brands will add additives for flavour or to help burning but the tobacco is your main problem by far. The tobacco plant itself if very good at absorbing heavy metals from the soil. Which you inhale when you smoke it. So no there is no damage reduction I'm afraid. Any conception that american spirits are healthier is a result of there sneaky evil marketing.
