As delegates gather for the World Health Organization's (WHO) biennial conference on tobacco, the authors of a new report, "No Fire, No Smoke: Global State of Tobacco Harm Reduction," are fiercely criticizing the WHO's record. The public health experts accuse the WHO of failing to comply with international treaty obligations to back reduced-harm alternatives to smoking. They deplore that the WHO instead recommends bans on e-cigarettes—a move that has been implemented by dozens of countries.
