South Asia's evolving tobacco hydra: moving from quandary to hope.

The South Asian region occupies a unique place in global tobacco control because of a broad spectrum of widely used tobacco products and the consequent mix of local and transnational tobacco industries. Cigarette use is especially high among males in many countries, while bidis are widely used in India, Bangladesh and Sri Lanka, and are very inexpensive. Smokeless tobacco use is a global problem, but the bulk of use is in South Asia and there is emerging promotion of newly developed tobacco and nicotine products across the region. With the transnational cigarette industry contributing a significant amount in taxes, the bidi industry employing millions of workers and many farmers engaged in tobacco farming, the industry is powerful and exploits this when countering proposed advancements in tobacco control policy. Despite industry interference and major challenges, this region has achieved remarkable successes in tobacco control, including large pictorial warnings that cover up to 80%-90% of the pack in some countries, stringent rules on depiction of tobacco in movies, bans on advertising and promotion, and smoke-free public places. Key challenges include increasing the tax component of retail prices and reducing tax concessions, regulating newly developed products and countering the aggressive tactics of the tobacco industry. Strategies to advance tobacco control in the region may also include standardised packaging of tobacco products, sustained mass media campaigns to warn the population of the harms of tobacco use and promote use of available cost-covered cessation services, and supply-side measures such as vendor licensing.
