More than 9 out of 10 women die from lung cancer than from breast cancer.
Pulmonary embolism (COPD) caused by continuing to smoke leads to death by more than 80%.

Tobacco and immunity

Tobacco use is very harmful because the main component of cigarettes is made up of several compounds that act as immunosuppressants, namely nicotine, formaldehyde, ammonia, carbon monoxide, benzopyrene, tar, acetone, hydroxyconone, cadmium and nitrogen oxides.

The disadvantages of nicotine

1- Decreased judicial pharyngeal activity

2- Chemical affinity and cell signals

3-  Inhibiting the release of reactive oxygen species (ROS) and thus impair the ability of neutrophils to kill pathogens.

The negative effects of the smoker

Smoker becomes more susceptible to coronary heart disease, stroke, and lung cancer, which causes deterioration of public health as a result of weak immunity, which increases absenteeism from work and increases the burden on health care and its cost, which affects public health. The country’s economic growth.

Cardiovascular disease and smoking

A smoker suffers from cardiovascular disease, which leads to stroke and coronary heart disease.
Smoking destroys vital body organs by raising blood pressure, causing clots that prevent blood flow to parts of the body and its organs, and harms immunity that is weakened due to neglect.
Smoking reduces blood flow to your legs and skin, so the body becomes unable to perform the tasks you want and harms the freshness of your face, and weakens the components of the skin, which is the first defense component of the immune system.

Smoking and respiratory diseases

When you smoke a lot, you create small air sacs in your lungs, and this is a major factor in chronic obstructive pulmonary disease and appears as emphysema and chronic bronchitis.

What are the harmful effects of smoking on the lungs?

The harms can be summarized in the following points:

1- Smoking inside the lungs leads to a series of inflammatory factors in which macrophages destroy tissues.

2- Increasing the secretion of inflammatory factors that lead to persistent chronic inflammation.

3 – Decreased macrophage capacity due to smoking which leads to its death

The above points affect the body’s immunity and become vulnerable to various infections and diseases.

Health risks and cancer

Due to frequent infections that weaken immunity, a smoker becomes more likely to develop cancer and illnesses anywhere in the body, such as:
Kidneys and ureters
Oropharynx (includes parts of the throat, tongue, soft palate, and tonsils)
Trachea, bronchi, and lung
Blood (acute myeloid leukemia)
Colon and rectum (colon and rectum)

Weak immunity and its impact on pregnant women

Nicotine in the blood.

The brain and nicotine

The brain is one of the most important elements of the body and through various studies, we can summarize the harms of smoking in the following points:
1- On the behavior of smokers, there is a negative effect on the nerve cells in the brain and this explains the difficulty smokers face in quitting smoking and the presence of a great psychological dependence on cigarettes.
2- Smoking causes profound changes within the immune system characterized by mixed inflammation and suppression of immunity throughout the body. Recent studies have shown that the brain may have a much weaker neurological immune response to infection and systemic infections, although there are no differences in primary immune activation.
3- The affected brain regions are the main regions that participate in stimulation and desire to increase the rate of smoking cigarettes and thus increase the proportion of nicotine and increase harmful

In particular, cigarette smoke acts as a double-edged sword that either exacerbates pathological immune responses or attenuates the normal defensive function of the immune system.
