Best NONE: Both direct and secondhand smoking of tobacco (and marijuana) are unsafe. 15% of smokers (>100 cigarettes in a lifetime) develop lung cancer. Even one per day is >300 cigarettes a year. 80% of all lung cancer is caused by smoking. Additionally, numerous other diseases and cancers are related to smoking. Please speak with family physician, respect yourself and be well.

100: 100 cigarretes on a lifetime increases risk for at least 10 years. However about 20% of smokers end up with lung cancer on their lifetime.However everybody does get emphysema to various degrees and accelerated arteriosclerosis triggering heart attacks and strokes at a younger age by persistent cigarrete smoking.Animal experiments dogs usually get cancer after 13, 000cigs.

How many cigarettes could get cancer?

One...: Cigarettes are not safe at all and there is no safe number of cigarettes. Even people that have only been exposed to second hand smoking could potentially get cancer. One of the best things people can do for their health is to stay away from cigarettes or cigarette smoke. Best wishes, ariel.
