Has anybody studied the effects of cigarette smoking on the atmosphere?
Although, pollution caused from cigarette smoking is nil. There is a radioactive interaction when it is inhaled into the lungs producing a radioactive gas. The name of it slips my mind, It sounds like plutonium but it is not plutonium. That is actually what causes the cancer. It causes more cases of lung cancer than radon. If smoking in a building, that gas and nicotine can last for hours contained in a poor ventilated area. I had to do some research with this because of learning radiation safety and reading chest x-rays. As far as the CO2 goes, we exhale that anyway. But there are other gases that the cigarrette produces that is harmeful. This pollution is not as bad as a trip to the store in a gas guzzeling car.
