New study warns of health risks from thirdhand smoke
A new US study warns of the risks of thirdhand smoke when cigarette particles infiltrate materials like hair, clothing, and furniture.

A new study from the United States, published in the journal Environmental Science and Technology, warns about the risk of "third-hand" smoke when particles from cigarettes seep into materials like hair, clothing, and furniture.

Researchers at the Berkeley Lab in California conducted a series of experiments on both humans and mice.


In a study, three non-smoking volunteers were asked to wear clothing that had been worn by heavy smokers for a duration of three hours.


Tests showed that after the experiment, the levels of toxic compounds NNK and NNN in their urine were as much as 86 times higher.


In another study, researchers exposed human lung tissue to the same carcinogens and indicated that they would cause DNA damage, which is one of the causes of cancer.


These findings illustrate the potential health effects of third-hand smoke. Third-hand smoke not only contains tobacco-specific nitrosamines (TSNAs), but also hundreds of other chemicals, some of which are known carcinogens," said Dr. Neil Benowitz, a physician at the University of California, San Francisco and author of the study.


The next step in this research will involve a more detailed exploration of the negative health effects associated with tobacco and cannabis residue, effective remedial strategies, and translating scientific findings into tobacco control practices.
