A recent study conducted by thirdhand smoke researchers from Lawrence Berkeley National Labs and their colleagues from Nanjing and Shenzhen, China shows that thirdhand smoke may both start and fuel cancer development. Growing evidence suggests that lingering thirdhand smoke can damage DNA and further accelerate cancer growth in cells. In other words, it may act as both an initiator and a promoter in the multistep process of tumor formation, making even low-level exposure a serious concern, especially for children and people with repeated contact.
