The dangers of secondhand smoke and how to protect ourselves

Passive smoking refers to the reluctance of a person who does not want to smoke to inhale the smoke from others and the smoke emitted in the environment when a cigarette is burned. Passive smoking is also known as "forced smoking", "indirect smoking" and "secondhand smoke". Because passive smoking inhales several to 50 times more toxic substances than active smokers, they can invade the lungs and damage the cells lining the arteries, promoting atherosclerosis.

In addition to lung cancer, it can also cause brain cancer, thyroid cancer, breast cancer, cervical cancer, etc. The smoke emitted by smoking is called "mainstream smoke" when smoked into the mouth of the smoker, and the smoke emitted from the tobacco is called tributary smoke. The carbon monoxide content in tributary smoke is 5 times that of mainstream smoke, the content of nicotine and tar is 3 times that of mainstream smoke, and the content of other harmful substances, including benzopyrene, which has carcinogenic effects, is also higher than that in mainstream smoke.

For smokers, long-term smoking has made their cardiopulmonary function adapt to the smoking environment, and their blood environment has been in a smoking state for a long time, and has produced "antibodies" or "adaptations" to the exhaled smoke. And for non-smokers, they are particularly sensitive to smoke and more harmful. In the past, it was believed that the harm of cigarettes was nicotine, but modern studies have shown that the harm of cigarettes is multifaceted, in addition to nicotine and tar, benzopyrene in combustion smoke is more harmful.

Passive smoking, also known as indirect smoking, refers to the process by which a non-smoker is exposed to the smoke caused by the smoker and is forced to inhale the smoke of the environment. Passive smokers are mainly women, children and infirm people who do not smoke normally, and their own resistance is weak, so the impact is greater.

Secondhand smoke is more harmful and has a higher chance of getting sick than smokers, and we should stay away from such places.

Terrence O'Neill and Tom Hefernam, members of the Drug and Alcohol Research Group at the University of Semibria, compared the memories of 27 smokers and two groups of non-smokers.

The first group of 27 non-smokers regularly inhaled secondhand smoke. They either live with smokers or spend a lot of time with smokers. For about four and a half years, an average of 25 hours per week were exposed to secondhand smoke.

The second group of 29 non-smokers was infrequent in second-hand smoke. The researchers tested three groups of volunteers with two methods, namely memories of future events and activities. One of the tests is to ask volunteers to remember a specific time before participating in an activity, and the other is to ask them to remember a future event or activity.
