New study highlights smoking intensity in coronary heart disease risk

(Oxford University Press USA) Increased relative risks for coronary heart disease (CHD) have long been associated with smoking, and traditionally they have been dependent on the number of cigarettes smoked a day, smoking intensities, and total exposure over time. A study published today in Nicotine & Tobacco Research suggests relative CHD risk is higher for smokers consuming cigarettes over a longer period of time than for smokers consuming the same quantity over a shorter period.
