Passive smoking occurs when someone who is not smoking breathes in tobacco smoke, such as cigarette smoke. It is also known as secondhand smoke.   

 

Secondhand smoke is a combination of the smoke produced from the lit end of a cigarette (or other combusted tobacco product) and the smoke exhaled by smokers. Public health authorities have concluded that secondhand smoke from burning tobacco causes diseases, including lung cancer and heart disease, in nonsmoking adults, as well as conditions in children such as asthma, respiratory infections, cough, wheezing, otitis media (middle ear infection), and sudden infant death syndrome. In addition, public health officials have concluded that secondhand smoke can exacerbate adult asthma and cause eye, throat, and nasal irritation.  People should be informed about these conclusions and guided by them in deciding whether to be in places where secondhand smoke is present or, if they are smokers, when and where to smoke around others. Smokers should not smoke around children or pregnant women.

What is passive smoking?

Passive smoking is the act of unintentionally inhaling nearby sources of tobacco smoke. This can happen if one is standing too close to a smoker who is smoking a cigarette, or even if one is too close to the lit end of a cigarette. Once cigarette smoke is in the air, it has the potential to be inhaled by those in its vicinity. Is passive smoking worse than smoking? Public health authorities have concluded that the secondhand smoke causes certain diseases as mentioned above.

How to create a smoke-free environment?

 

If you are an adult smoker, here are some tips on how to create a smoke-free environment.  

 

Quit smoking entirely. The best way to eliminate secondhand smoke is to quit smoking. This is of course the best course of action for any smoker. Smokers should not smoke around children or pregnant women. 

 

Make the house smoke-free. It’s not enough to just open a window or door, or smoke in another room of the house. Smoke can linger in the air after you’ve had a cigarette. People should be guided by public health authorities’ conclusions in deciding whether to be in places where secondhand smoke is present or, if they are smokers, when and where to smoke around others. 

 

Make the vehicle smoke-free. Similar to smoking in the house, the car is another enclosed space best left smoke-free. Having the windows down in a car will not make a big difference, as smoke can cling to the car seats and linger in the air. People should be guided by public health authorities’ conclusions in deciding whether to be in places where secondhand smoke is present or, if they are smokers, when and where to smoke around others.  

 

Respect smoke-free zones. Be aware before you light up a cigarette and observe the area around you carefully - especially if you are traveling and unfamiliar with local laws and customs.   
 

 

Is aerosol produced by tobacco heating devices harmful to non-smokers?

 

The best decision any smoker can make is to quit tobacco and nicotine use altogether. For adult smokers who would otherwise continue to smoke or use nicotine products, there are many smoke-free alternatives on the market today, and a tobacco heating device is one option that is available. In general, tobacco heating devices do not produce smoke as they do not burn tobacco, but rather, they heat tobacco to create a vapor.  

 

With that in mind, many wonder if tobacco heating devices produce secondhand smoke. In general, tobacco heating devices should not burn tobacco or generate tobacco smoke and therefore have the potential to emit significantly fewer and lower levels of harmful and potentially harmful chemicals compared to cigarette smoke. The lack of combustion and the reduction in formation of harmful chemicals should be substantiated on a product-by-product basis. Importantly, this does not mean that smoke-free products including usage of tobacco heating devices are risk free. Without question, the best decision any smoker can make is to quit tobacco and nicotine use altogether.

Is e-cigarette vapor harmful to non-smokers?

 

Electronic cigarettes, or vapes, are another kind of smoke-free alternative available for adults who would otherwise continue to smoke or use nicotine products. E-cigarettes are considered a smoke-free alternative as usually they heat an e-liquid to produce a vapor or aerosol, rather than create smoke from burning tobacco.

With that in mind, many wonder if vaping produces secondhand smoke. In general, e-cigarettes should not burn liquid or generate smoke and therefore have the potential to emit significantly fewer and lower levels of harmful and potentially harmful chemicals compared to cigarette smoke. The lack of combustion and the reduction in formation of harmful chemicals should be substantiated on a product-by-product basis. As the Vapor market is very heterogeneous, including open systems with personalized e liquids, a general statement regarding harm reduction is more difficult. Importantly, this does not mean that smoke-free products including e-cigarettes are risk free. Without question, the best decision any smoker can make is to quit tobacco and nicotine use altogether.  

 

Smoke-free product users, including tobacco heating devices and e-cigarettes, should always be mindful of others before using any nicotine containing products around non-smokers, minors and people with certain medical conditions and pregnant women.
