Answer:
c. chewing tobacco can cause cancer
Explanation:
Chewing tobacco is not a harmless alternative. Quite the contrary according to countless scientific research. It is true that while chewing tobacco you do not aspire to carbon monoxide, but nicotine levels are equally high, increasing the risk of developing high blood pressure and cardiovascular disease. Not to mention, of course, the risk of the dreaded oral cancer, larynx, pharynx, esophagus and even the brain, which can reach a level 50 times higher than a person who does not smoke. As the danger of chewing tobacco has been proven kinetically, we can claim that this is a scientific fact.
