Smoking unfiltered cigarettes poses a greater risk of lung cancer than smoking filtered cigarettes, according to a study published in JAMA Internal Medicine.
Among the 14,123 patients included in the study, those who smoked unfiltered cigarettes were 40 percent more likely than those who smoked filtered cigarettes to develop lung cancer and almost twice as likely to die of lung cancer.
Researchers noted that although the risk was greater in those who smoked unfiltered cigarettes, those who smoked filtered cigarettes are also at a great risk. The study demonstrated lung cancer deaths occur in 1,600 per 100,000 persons who smoked filtered cigarettes compared with just 34 per 100,000 persons who never smoked.
