Tobacco control is a field of international public health science, policy and practice dedicated to addressing tobacco use and thereby reducing the morbidity and mortality it causes. Since most cigarettes and cigars and hookahs contain or use tobacco, tobacco control also addresses these products. Tobacco control is a priority area for the World Health Organization (WHO) as a part of the Framework Convention on Tobacco Control. References to a tobacco control movement may have either positive or negative connotations, depending upon the commentator.
