How much dangerous is smoking

Medical researchers and health care providers traditionally viewed this level of low-intensity smoking as a temporary practice among people who are trying to quit, the study says.

However, research indicates that many low-intensity smokers maintain these smoking patterns for many years over their lifetime. Smoking duration is a substantially more important factor for disease risk than the number of cigarettes per day, the study says. Many people, particularly those who are younger, erroneously believe that smoking a few cigarettes a day or a week is fairly safe, says pulmonologist Humberto Choi, MD.

Choi, who specializes in thoracic oncology and critical care, did not take part in the study. Choi says. Light, long-term smokers who quit were able to lower their risk of death — and the younger they were when they quit, the better, the study says.
