World No Tobacco Day 2025
31 May is World No Tobacco Day (WNTD). In May 2025 WHO and public health champions from across the globe will come together for WNTD to raise awareness about the harmful tactics of the tobacco industry.
This year's WNTD campaign aims to reveal the strategies employed by the tobacco and nicotine industries to make their harmful products enticing, particularly to young people.
By exposing these tactics, WHO seeks to drive awareness, advocate for stronger policies, including a ban on flavours that make tobacco and nicotine products more appealing, and protect public health.
