The Invisible Threat: Secondhand Smoke

Raising awareness about secondhand smoke is not just about statistics and figures; it's about the well-being of the populace. It's about encouraging not just quitting smoking but eradicating it from every corner of our lives, for the sake of those who do not have the choice. It is important to arm ourselves with knowledge on the perils of secondhand smoke and act proactively. Whether it’s through personal lifestyle changes, supporting smokes cessation policies, or seeking help for friends and family who smoke, every action, no matter how small, moves us one step further away from secondhand smoke and towards healthier lives.

  Secondhand Smoke: The Science

Scientific evidence has firmly established that there is no safe level of exposure to secondhand tobacco smoke, a pollutant that causes serious illness in adults and children. There is also indisputable evidence that implementing 100 percent smokefree environments is the only effective way to protect the population from the harmful effects of exposure to secondhand smoke.4

 Demystifying Secondhand Smoke: What You Need to Know

Every day, whether we realize it or not, many of us are exposed to a significant yet avoidable risk to our health—secondhand smoke. This invisible hazard can pervade the spaces where we live, work, and socialize, creating various potential health problems. At its core, secondhand smoke (SHS) is the smoke that is exhaled or otherwise released from a burning tobacco product, such as a cigarette, cigar, or pipe. However, it's not just the smoke the smoker inhales and exhales that poses a risk. "Side-stream" smoke, which comes directly off the burning end of a tobacco product, also contributes to secondhand smoke. As such, even if you're not the one actively smoking, but you're in the vicinity of someone who is, you're still inhaling many of the same harmful substances. Secondhand smoke is composed of thousands of chemicals, many of which are toxic, and over 70 are known carcinogens. These chemicals infiltrate our bodies, causing a myriad of adverse health effects. Secondhand smoke has no safe level of exposure, and even short periods of contact can pose significant health risks.

Can Secondhand Smoke Lead To Weight Gain?

You may want to hold your breath. No, not because there is flatulence around you (although there may be.) Prior studies have shown that smoke from people smoking around you (otherwise known as secondhand smoke) can lead to many of the same medical problems that smokers face, such as lung cancer and heart disease. Now a recent study published in Childhood Obesity suggests that secondhand smoke exposure can be associated with obesity and impaired thinking in 7-to-11-year-old children.

Childhood exposure to lead can limit cognitive development and cause a drop in IQ

We found that the average blood lead levels in the intermediate and high tobacco smoke exposure groups were 18% and 29% higher, respectively, than those in the group with the lowest tobacco smoke exposure. The lowest lead exposure group was comparable to the U.S. average. A greater number of boys had detectable lead levels in their blood, as did a greater number of Black children and adolescents, compared with the other ethnic groups we studied.

Damning Evidence Against Secondhand Smoke

"There is no level of exposure to secondhand smoke that is safe. Period," says Jonathan Samet, professor and chair of Epidemiology and senior scientific editor of the Surgeon General's 2006 report on the devastating health consequences of secondhand smoke exposure.

Health effects associated with exposure to secondhand smoke: a Burden of Proof study

Despite a gradual decline in smoking rates over time, exposure to secondhand smoke (SHS) continues to cause harm to nonsmokers, who are disproportionately children and women living in low- and middle-income countries.

How Secondhand Cigarette Smoke Changes Your Genes

It’s not clear how permanent these genetic changes are, but previous data suggests that, at least in smokers, some of the alterations may be irreversible. Smokers experience a decline in lung function that is accelerated compared with nonsmokers, and even if they kick the habit, they can never achieve the same level of function as those who never lit up.

Is It Safe Yet to Have an Honest Conversation About Secondhand Smoke and Lung Cancer?

Several years ago I was talking to an epidemiologist who is skeptical of the idea that smokers pose a mortal threat to people in their vicinity. Although he supported workplace smoking bans, he was frustrated by the willingness of so many anti-tobacco activists and public health officials to overlook or minimize the weakness of the scientific case that secondhand smoke causes fatal illnesses such as lung cancer and heart disease.

Is your pet exposed to secondhand smoke? Here are the (serious) health risks

Cancer is commonly diagnosed in dogs and is a significant cause of death. While many factors may predispose a pet to developing cancer, evidence suggests that passive smoking is a key risk. Scottish terriers living in homes where they were exposed to cigarette smoke were six times more likely to develop bladder cancer than those not routinely exposed. Nasal cancer in dogs is also linked to passive smoking, and is a particular problem for dogs with long muzzles, such as collies. This is compared to a lower incidence of nasal cancer, but higher risk of lung cancer in brachycephalic, or short-nosed breeds such as pugs.

Secondhand bong smoke worse than that from tobacco, study finds

The fine particulate matter in cannabis smoke from bongs is at least four times greater and more dangerous, experts said.

Secondhand Smoke

We have known for at least 30 years, since the 1993 Environmental Protection Agency (EPA) Risk Assessment, that secondhand smoke is a Group A Carcinogen, known to cause cancer in humans. More recent research reveals that there are immediate health risks, including asthma and heart attacks.

Secondhand Smoke Is Bad For Smokers, Too

Smokers these days have been all but banished to sidewalks or cramped smoking lounges, but those smoking lounges may make a bad habit even worse for smokers' health A new study published in the journal Environmental Health finds that people who smoke in confined spaces inhale enough secondhand smoke to add significantly to their health risks from smoking.

Secondhand Smoke May Affect Mental Health

All you have to do is look around at the growing number of smoking bans in workplaces, restaurants, bars and airplanes to appreciate how seriously officials take the health risks of smoking. And in public places, that applies as much to the nonsmokers who are exposed to the potentially dangerous effects of cigarette smoke as it does to the smokers themselves.

Secondhand smoking is causing thousands of stillbirths in developing countries

Pregnancy is a vulnerable time for a woman’s health and tobacco smoke harms mothers and their unborn children. In developing countries it is uncommon for women to smoke while pregnant – but their exposure to secondhand smoke during pregnancy is a lot higher, according to a recent study by the Demographic and Health Survey which was carried out in 30 developing countries and published in Tobacco Control.

The case for banning smoking indoors — even in your home

Although it gets considerably less press than it previously did, smoking remains a huge threat to public health. According to the Centers for Disease Control and Prevention’s most recent data, smoking kills 480,000 people each year. Secondhand smoke alone kills nearly 42,000 people. To put that in perspective, that’s around 8,000 more people than die to either car crashes or gun violence. So we’re clearly dealing with a major public health crisis. And the research shows that smoking bans can help, particularly with eliminating exposure to secondhand smoke.

The Dangers of Secondhand Smoke

Secondhand smoke is more than simply another annoying smell (“What’s That Smell?” Aug. 6). It’s a toxic soup of hazardous chemicals, and, according to a recent surgeon general’s report, any level of exposure increases the risk of serious diseases. According to a recent Zogby poll conducted for the New York City Coalition for a Smoke-Free City, more than 50 percent of those surveyed expressed a willingness to pay more to live in a smoke-free building.

We Used Terrible Science to Justify Smoking Bans

Will we look at the new evidence for long enough to at least consider whether we’ve gone too far?

What evidence is there that passive smoking kills?

Well, common sense for a start. But that won't normally do for scientists. So how about a worldwide review of research in the field, pulled together and published by 40 epidemiologists for the World Health Organisation in June, that concluded that secondhand smoke increased the risk of lung cancer by 25%? "We have quite a body of evidence building up over the last 20 years," says Sinead Jones, director of the tobacco control resource centre at the British Medical Association (BMA).

When Your Neighbor’s Secondhand Smoke Invades Your Home

You may not be a smoker, but if you live in an apartment or condo your neighbor’s cigarette smoke may be infiltrating your abode. This secondhand smoke is well-documented health hazard. Here are some steps you can take to avoid this problem.

Yikes: A New Study Says Being Around People Who Smoke Can Mess With Your Fertility

It's been drilled into us since we were kids: Smoking is really, really bad for you. But new research has found that simply being around smokers can do just as much damage to your fertility as if you were the one lighting up. For the study, which was published in the journal Tobacco Control, researchers from the Roswell Park Cancer Institute analyzed data from nearly 94,000 women and discovered a shocking link between secondhand smoke and infertility. Scientists learned that women who are regularly exposed to secondhand smoke have a 15 to 20 percent greater risk of infertility than those who aren't around smokers, as well as a higher risk of going into early menopause.
