'Thirdhand' smoke can be dangerous too

According to a new study by the Yale University, thirdhand smoke, the residue tobacco contaminants that adhere to walls, bedding, carpet and other surfaces, can actually cling to a smoker's body and clothes as well. These potentially toxic chemicals can then be released into environments where smoking has never occurred. The study may be the first to show that people can transmit nicotine and other potentially toxic chemicals via their clothing long after active smoking is over. Researchers set up an experiment in a movie theater that had not allowed smoking for more than 15 years. Sophisticated equipment measured airborne particles before and after moviegoers arrived. They saw a huge spike in levels of hazardous chemicals.
