Smoking Bans Don't Prevent You Having To Breathe in Smoke Particles

You can breathe in harmful chemicals from tobacco use even in non-smoking venues because they are carried on smokers' bodies and clothes. From a report: Third-hand smoke -- the residue from cigarette fumes that sticks to surfaces and then wafts back into the air -- has previously been found indoors in places where smoking is allowed. To find out if third-hand smoke also pollutes non-smoking venues, Drew Gentner at Yale University and his colleagues monitored the air quality in a non-smoking cinema in Germany for four days, after first flushing it with clean air. Smoking is banned inside cinemas and other public places in Germany. They observed spikes of tobacco chemicals in the air just after audiences arrived, which decreased over time but didn't go away completely. The polluting substances were probably brought in on the bodies and clothes of people who had recently smoked cigarettes or been near smokers, says Gentner. They observed larger spikes during movies rated for those aged 16 and above, most likely because the audiences were older and had greater tobacco exposure than those attending movies suitable for younger people, says Gentner. The amount of tobacco chemicals that people watching the films aimed at older teens and adults were exposed to per hour was equivalent to that inhaled while sitting directly next to someone as they smoke up to 10 cigarettes.
