China: At the 20th National Academic Seminar on Tobacco Control and Health, Zhi Xiuyi, vice-president of the Chinese Association on Tobacco Control, said e-cigarettes contain various carcinogens and harmful substances. Xiao Lin, director of the Tobacco Control Office of the Chinese Centre for Disease Control and Prevention, reported that, in 2023, the e-cigarette usage rate among Chinese middle school students was 2.4% – a decrease of 1.2 percentage points compared with 2021, representing a reduction of over 30%.
