The study published in The Lancet Public Health said that despite worldwide progress since the WHO Framework Convention on Tobacco Control (WHO-FCTC) came into effect in 2005, not all key demand-reduction measures have been fully implemented and doing so could reduce tobacco use even further.
The treaty obligates the 180 countries committed to it to implement strong evidence-based policies, including five key measures -- high tobacco taxes, smoke-free public spaces, warning labels, comprehensive advertising bans, and support for stop smoking services.
India signed the treaty in September 2003 and ratified in February 2004, according to the UN website.
The study was conducted by a team of researchers from the International Tobacco Control Policy Evaluation Project, based at the University of Waterloo in Canada and the World Health Organization in Geneva.
