With a New Year comes a new resolution - to take better care of oneself. For some, this means quitting smoking. It's not an easy resolution to accomplish, but new research published this week may provide additional encouragement to those trying to kick the habit. Researchers have given a name to the invisible, lingering effects of cigarette smoke called "third-hand smoke".
First, Second, and Third-Hand Smoke
Let's define first-hand smoke and second-hand smoke. First-hand smoke is what a smoker inhales. This smoke is toxic to the smoker, but cigarette filters may help reduce some toxins. Second-hand smoke, or environmental tobacco smoke (ETS), is a combination of the smoke from the burning end of a cigarette and the smoke exhaled from smokers. This smoke can linger in the air for hours, and is inhaled involuntarily by nonsmokers. Second-hand smoke can pose serious health risks to nonsmokers even though they were not smoking directly.
Researchers from MassGeneral Hospital for Children in Boston, Massachusetts describe third-hand smoke as what remains after second-hand smoke is gone. Third-hand smoke refers to the gases and particles that linger in hair, and on clothes or fabrics. Some of what remains includes hydrogen cyanide, butane, toluene, arsenic, lead, carbon monoxide, and polonium-210.
Reasons Behind the Study
The study done at MassGeneral Hospital is published in the most recent issue of Pediatrics, and focuses on the harm that third-hand smoke can have on children and infants. Researchers claim that many parents don't realize the risk of third-hand smoke. "Everyone knows that second-hand smoke is bad, but they don't know about this," explains Dr. Jonathan P. Winickoff, the lead author of the study and assistant professor of pediatrics at Harvard Medical School.
According to parents surveyed in the study, third-hand smoke isn't something that is known about. They've found ways to get "rid" of second-hand smoke – by turning on a fan, opening a window, waiting until the kids are outside to smoke, etc. Once the visible smoke was gone, the parents assumed that the air was safe for their children. According to Dr. Winickoff, the term third-hand smoke was coined to give name to the invisible toxins left behind from tobacco.
Implications
Philip Landrigan, a pediatrician who heads the Children's Environmental Health Center at Mount Sinai School of Medicine in New York, believes that third-hand smoke is a term that has implications for behavioral change. "The central message here is that simply closing the kitchen door to take a smoke is not protecting the kids from the effects of that smoke…There are carcinogens in this third-hand smoke, and they are a cancer risk for anybody of any age who comes into contact with them."
Cigarette smoke is so distant and strong that it's important to know that just smelling it could be harmful. However, the most interesting thing I came across when reading about this topic is the question of whether the implications of third-hand smoke are an "alarm too far". Granted, the question comes from someone's blog, but I thought it was a good question for CR4 readers.
The blogger asks their readers, "Is this just a logical extension of the dangers that we already understand about exposing children to tobacco smoke or is it an alarm too far that will alienate parents who already know that they shouldn't be smoking around their children?"
I am posing the above question to all of you. What do you think?
