More than five million people die as a result of smoking tobacco each year, according to a report published by the World Health Organization (WHO).

WHO says that an additional 600,000 people are also estimated to die from the effects of second-hand smoke.

It says tobacco kills more than tuberculosis, HIV/AIDS and malaria combined.

The agency describes tobacco as “the only legal drug that kills many of its users when used exactly as intended by manufacturers.”

Patrick Maigua discussed this problem with Dr Edouard Tursan d'Espaignet, from the WHO Tobacco Free Initiative Department.
