New things are being discovered everyday. Smoking which used to be hip and groovy some decades ago is no longer encouraged when found that it is bad for health. We even found that second-hand smoke is hazardous to people who do not smoke but who are exposed to the cigarette fumes. Now, scientists have discovered something called third-hand smoke.
What is third-hand smoke? According to the New York Times, it is the invisible yet toxic brew of gases and particles clinging to smokers’ hair and clothing, not to mention cushions and carpeting, that lingers long after second-hand smoke has cleared from a room. The residue includes heavy metals, carcinogens and even radioactive materials that young children can get on their hands and ingest, especially if they’re crawling or playing on the floor.
Third-hand smoke is what one smells when a smoker gets in an elevator after going outside for a cigarette, or in a hotel room where people were smoking. -- Now, this is close to home as the elevators in my office buildings are sometimes wreaked with cigarette smell from clothes of people who have just come in from the smoking area.
Why is third-hand smoke bad for health? Among the substances found in third-hand smoke are hydrogen cyanide, used in chemical weapons; butane, which is used in lighter fluid; toluene, found in paint thinners; arsenic; lead; carbon monoxide; and even polonium-210, the highly radioactive carcinogen that was used to murder former Russian spy Alexander V. Litvinenko in 2006. Eleven of the compounds are highly carcinogenic.
