Is light smoking harmful?
Light and social smoking carry cardiovascular risks. Light smoking isn’t as bad as heavy smoking, but it still harms the heart and body. If you quit smoking completely, your health will benefit.

How bad is an occasional cigarette?
Just one to four cigarettes a day almost triples your risk of dying from lung cancer. And social smoking is particularly bad for your heart, as bad as regular smoking, it seems. Studies have shown light and intermittent smokers have nearly the same risk of heart disease as people who smoke daily, Professor Currow said.
