I’m agree with all physical activity may not be associated with a lower likelihood of adolescent smoking uptake topic. Because Young smokers are more likely to report suffering an overall diminished level of health compared with non-smokers.

There are limited data on population beliefs of the benefits of smoking cessation. There is a strong belief among smokers that stopping smoking will improve their health.
