Yes, but then you wouldn't get the benefits of participating in sports, such as better cardiovascular health, improved stamina, the social benefits of learning to play as a member of a team, and yes, even resistance to injury that comes from proper sports training.
What health and social benefits would you miss out on if you quit smoking?
Stress relief. Stress causes Hypertension. Hypertension causes heart disease. Heart disease is the number one cause of death in America.
(I'm BSing. There are no health advantages to smoking. For me it's a personal right issue)
