(SOUTH CHINA MORNING POST) — Electronic cigarettes were found to contain one million times more cancer-causing substances than outdoor air in a study by Baptist University.
Researchers also discovered a type of flame retardant that affected the reproductive system and could lead to cancer – the first such discovery in e-cigarettes.
The Hong Kong Council on Smoking and Health, which commissioned the study, called for a ban on e-cigarettes as soon as possible before they become more popular.
