A study conducted by Dr. Giovanni Invernizzi and a team of researchers from Tobacco Control Unit of Italy's National Cancer Institute. The researchers analyzed these two types of smoke in an experiment located in a garage in a small village with very low pollution levels in Northern Italy.
The first experiment was carried out by switching on a 2-liter diesel engine with a low sulfur diesel fuel for 30 minutes inside the garage with a closed door. After that, another experiment was performed by lighting three filter cigarettes for 30 minutes in the same room. The result is, the first experiment where the only light is diesel engine and there is no smoke, it is known that the level of air pollution in the garage reached 88 ug / m3. Once added to cigarette smoke, the level of air pollution is soaring to 830 ug / m3 or almost 10 times larger.
Dr. Invernizzi mentioned that he and his team were quite surprised by the striking difference of air pollution levels released by the smoke of motor vehicles and cigarette smoke. He also concluded that although both are equally harmful to health, cigarette smoke proved to have more terrible ability in damaging the health of our bodies.
There have been many other studies that mention that in a single cigarette, there are more than 4 thousand toxic chemicals and 43 compounds that are carcinogenic or can trigger cancer. These various contents are clearly very harmful to our body's health.
