Risk of premature birth
One of the biggest risks of using e-cigarettes during pregnancy is the risk of premature birth and low birth weight. Nicotine, a key ingredient in many e-cigarettes, can affect fetal development.
Nicotine can reduce blood flow to the fetus, depriving it of oxygen and nutrients it needs for growth. This can lead to premature birth and low birth weight, both of which can cause serious health problems later in life.
Risk of birth defects
One of the most common harmful effects of smoking on pregnant women is the increased risk of birth defects. The risk of birth defects in children increases whether the mother smokes directly or is exposed to secondhand smoke.

Abnormalities such as: Congenital malformations, cleft lip, cleft palate, asthma, cardiovascular disease, etc. Therefore, when pregnant, mothers need to immediately quit smoking and stay away from places where people smoke to ensure the health of both mother and baby.
Causes respiratory diseases, lung diseases, asthma
Chemicals in e-cigarette vapor, including volatile organic compounds and heavy metals, can damage the lungs and respiratory system of the fetus.
Babies born to mothers who used e-cigarettes during pregnancy are at increased risk of respiratory illnesses such as asthma and pneumonia.
Medical experts say that cigarette smoke contains more than 7,000 chemicals, including 69 carcinogens. It is the cause of 25 dangerous diseases, with lung cancer being the leading cause.
Talking about the dangers of cigarettes to the lungs, studies show that smokers are 10 times more likely to get lung cancer than non-smokers, which is the cause of more than 2/3 of lung cancer deaths worldwide.
Furthermore, about one-quarter of the world's population has latent TB infection, and is at risk of developing TB disease. But smokers are twice as likely to develop TB as non-smokers.
In patients with tuberculosis, if they continue to smoke, the combination of tuberculosis and the harmful effects of cigarette smoke significantly increases the risk of disability and death from respiratory failure.
In order to improve the quality of life, as well as help screen for lung cancer early, it is recommended to have regular check-ups or go to reputable medical facilities for examination if you have one of the following risk factors:
Regular smoking or passive smoking;
Weakness, fatigue, and unexplained weight loss;
Cough that persists and gradually gets worse;
Bloody sputum (Hemoptysis);
Shortness of breath, sneezing, or hoarseness;
Recurrent pneumonia and fever;
Frequent chest pain.
