We often hear about the health risks of second-hand smoke, or passive smoking, but now a new study reveals that third-hand smoke can be dangerous too.
Third-hand smoke is the term used to describe tobacco contaminants that stick to walls, carpet, bedding and other surfaces, leading to a room smelling like an ashtray. However, research by Yale University has revealed that third-hand smoke actually clings to a smoker’s body and clothes as well, allowing it to be released into environments where smoking has never occurred.
While this might not sound like too big a deal, the worrying revelation from the study is that non-smokers in such environments can be impacted. In fact, the study says chemical exposure in a movie theatre could be the equivalent of being exposed to between one and 10 cigarettes of second-hand smoke by the end of the movie.
Speaking about the findings of the research, Drew Gentner, study authord and an associate professor of chemical and environmental engineering at Yale University, said: “People are substantial carriers of third-hand smoke contaminants to other environments. So, the idea that someone is protected from the potential health effects of cigarette smoke because they're not directly exposed to second-hand smoke is not the case.”
