In a new report, the World Health Organization strongly urges governments to raise taxes on tobacco in a global effort to reduce the number of deaths from tobacco-related disease.

The solution proposed by the WHO is to raise taxes to more than 75% of the retail price. The organization claims this is “among the most effective and cost-effective tobacco control interventions,” costs little to implement and increases government revenues.

The report also contains guidelines on how to implement price and tax measures to reduce the demand for tobacco.

Despite the effectiveness of this high-tax intervention, the report notes that only a few countries have taken this step. By 2014, 33 countries had implemented high-tax measures, but still only 10% of the world’s population live in countries with tobacco taxes that WHO consider to be sufficiently high.
