Tobacco Cancer Gift

Tobacco industry does not like to lose sales. It even pays to fund scientific studies of second-hand smoking in order to prove to the public that it is not harmful to non-smokers. And here I do not understand something. Tobacco smoke is harmful to smokers. And how can it be not harmful to me when I inhale it?

It is interesting that chocolate is also considered harmful. People blame chocolate for their rotten teeth and extra weight. Scientists again have their opinions on the subject. But when I smell chocolate, it does not affect me a bit. Is it possible tobacco industry to change from burning tobacco to tobacco bars? In this way tobacco lovers will have their cancer, but I will have no cancer gift from them.
