Occasional smokers could run the same risk of heart disease as regular smokers، a study by the Ohio State University College of Nursing in Columbus has shown.
The study، published on Thursday، suggests that so-called social smokers، who only light up on special occasions، may equally be at risk of heart disease compared with people on a daily cigarette habit.
The researchers involved in the study examined data on smoking habits، cholesterol levels and blood pressure for a nationally representative sample of 39،555 adults.
Most people said they did not smoke. About 17 percent were current smokers and about 10 percent were social smokers who did not have a daily habit but did regularly smoke in certain situations.
