Tobacco is the second major cause of death in the world, after cardiovascular disease, and is directly responsible for about one in ten adult deaths worldwide, equating to about 6million deaths each year (Shafey et al., 2009). It is a
major risk factor for at least two of the leading causes of premature mortality ‐ circulatory diseases and a range of cancers. In addition, it is an important contributory factor for respiratory diseases, while smoking among pregnant women can lead to low birth weight
and illnesses among infants. It remains the largest avoidable risk to health in OECD countries.
