Secondhand smoke is a mixture of smoke from the burning end of a cigarette and smoke expelled by smokers. It contains nicotine and carcinogens such as nitrosamines and tar. Secondhand smoke also contains ammonia, phenols, and other chemicals that are toxic to humans.
Second-hand smoke is the term used to describe the effects of exposure to tobacco smoke that remains in the air after someone who smokes has gone through their usual smoking rituals. This includes both smoked and exhaled tobacco products. Second-hand smoke can affect anyone who comes into contact with it, including family members who may not think to themselves "I should probably stop breathing" but instead just feel unwell after being around smokers or after sleeping in rooms with smokers who haven't changed their habits recently. Even those who don't smoke are affected by second-hand smoke: it contains chemicals that cause respiratory problems for people with asthma or allergies; and there's some evidence that it may also be bad for children's lungs too.
Smoking causes cancer of the lung, bladder, kidney, mouth, throat, esophagus, stomach, colorectal cancer, acute myeloid leukemia, adult chronic lymphocytic leukemia (CLL), adult small cell lung cancer (SCLC).
Secondhand smoke includes about 7,000 compounds, hundreds of which are harmful and perhaps 70 of which can cause cancer.
Smokers who live with non-smokers are often unaware of the health risks they face from second-hand smoke. Even if they are aware of the dangers, many refuse to change their behavior because they do not want to affect their partners' comfort level or feel like it is their choice to make. However, studies show that when informed of the risks, most smokers will agree that smoking should not be done in homes with children or pregnant women present.
In addition to being harmful to your own health, second-hand smoke also poses a risk to infants born to mothers who smoke during pregnancy. Studies have shown that babies born to mothers who smoked during pregnancy are at higher risk for low birth weight, premature delivery, and infant death. They may also have respiratory problems later in life due to early exposure to pollutants found in tobacco smoke.
The best defense against second-hand smoke is not to smoke at all. If you must smoke, then try to do so in an environment where no one else can be harmed by your actions.
Secondhand smoke is classified into two types: mainstream smoke, which is inhaled by the smoker, and sidestream smoke, which is emitted from the cigarette's burning end.
The health effects of smoking on individuals are well known. However, smoking also has negative effects on the quality of life for non-smokers, including children living with smokers, people who work with or around smokers, and those who do not smoke but are exposed to smoke emissions through the air. These people are at risk of developing serious illnesses due to certain chemicals in tobacco products that are not found in equal amounts in other products such as cigars or pipe tobacco.
Children living with smokers face a higher risk of developing respiratory problems when they begin smoking at an early age. They also have a higher chance of developing cancer later in life. Children who live with smokers are also more likely to repeat a grade or drop out of school because they cannot concentrate on their education due to the presence of smoke in the home.
The American Cancer Society recommends that people not smoke at all if they want to protect others from breathing smoke toxins and themselves from getting sick through smoking. But if you can't give up cigarettes entirely, then minimizing your exposure to both mainstream and sidestream smoke is very important.
Secondhand smoke is a combination of smoke from the burning end of a cigarette, cigar, or pipe and smoke exhaled by the smoker. It has around 7,000 compounds in it. Hundreds of these substances are hazardous, and roughly 70 of them are carcinogenic. There is no such thing as a safe level of secondhand smoking. Even one cigarette burns millions of particles that can enter your body through your lungs or stay with you for hours after you extinguish it.
Cigarette smoke is the most harmful form of smoke available on the market today. Cigarettes contain nicotine and other chemicals that are highly addictive. They also contain carbon monoxide and hydrogen cyanide. All cigarettes not smoked in an enclosed space (such as a factory) contain carbon monoxide. Some contain ammonia, acetaldehyde, or acetic acid.
The smoke from a cigar or pipe contains many fewer toxic chemicals than cigarette smoke. However, there are still chemicals in cigar smoke that can be harmful to your health. Tobacco plants produce a chemical called nitrosamine which is known to cause cancer. This chemical is present in both cigarette and cigar smoke.
When you burn either tobacco or marijuana, natural chemicals are released into the air. These chemicals include ammonia, hydrogen cyanide, and phenol. Ammonia and hydrogen cyanide are dangerous if ingested while phenol can be fatal if enough enters your body. Everyone exposed to these chemicals should take precautions to protect themselves from possible harm.
