(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.
