This is scary

And how do we know that said tar was not affected by polonium and radiation, going on to cause COPD? There is no differentiation in the study, so it remains a grey area.

It is little known that the type of cigarette can affect the amount of damage done to a lung. There are rates of recovery, regeneration, etc.. as well as long term accumulative damage, all dependent on what is being smoked. All smoke is not the same.

i never claimed all smoke was the same, only that smoke related damage results from more than simply radiation. if you read the mechanisms by which smoke damages the lungs, you can see that it would do so reguardless of radioactivity, although radioactivity may contribute to the harm it does. it's ridiculous to assume that if one smoked a substance which was not radioactive it would not harm the lungs. just read the studies i posted earler on marijuana smoking related lung damage if you need proof of this.
