BOSTON, Aug. 5 (UPI) -- The majority of U.S. teens who use smokeless tobacco products also smoke cigarettes, researchers say.
Israel T. Agaku, Dr. Constantine I. Vardavas, Hillel R. Alpert and Gregory N. Connolly, all of the Center for Global Tobacco Control, Department of Social and Behavioral Sciences, Harvard School of Public Health in Boston; and Olalekan A. Ayo-Yusuf of the Harvard School of Public Health and the University of Pretoria in South Africa said the findings counter the idea smokeless tobacco products help reduce the health problems associated with tobacco use.
