“A recent study by Li and colleagues at the Second Affiliated Hospital of Chongqing Medical University in Chongqing, China, followed over 315,000 people who had never smoked. They found that exposure to secondhand and thirdhand smoke may increase the risk of liver cancer. Compared to those with little or no exposure, individuals exposed to daily secondhand smoke had a 36% higher risk of liver cancer and those exposed to thirdhand smoke had a 23% higher risk. The study also found that longer durations of secondhand smoke exposure were linked to even greater risk, with stronger effects observed in younger individuals.

This research highlights that all forms of tobacco smoke exposure contribute to serious long-term health risks, including liver cancer. This reinforces the importance of protecting people from all forms of smoke exposure”.
