The effects of tobacco and nicotine on the human health are serious because it harms almost every organ in the body. Here are some of the health problems linked to tobacco use:
 
1. Cancers
 
Tobacco is associated with a number of cancers, including the respiratory tract, lung, upper gastrointestinal tract, liver, pancreas, kidney, urinary bladder, oral cavity, nasal cavity, cervix, etc.
 
2. Cardiovascular diseases
 
The chemicals in tobacco harm your blood cells and damage the function of your heart, thereby increasing your risk for a heart attack, stroke, and coronary heart disease (CHD).
 

3.Respiratory diseases
Smoking is the most common cause of chronic obstructive pulmonary disease, which includes chronic bronchitis and emphysema. Smoking is associated with acute attacks of asthma. Smoking also substantially increases the risk of tuberculosis and death from TB.
 
4. Pregnancy complications
 
Smoking during pregnancy can harm the mother as well as the baby. Women who smoke during pregnancy are more likely than other women to have a miscarriage, stillbirth, an ectopic pregnancy. Smoking can also cause bleeding during pregnancy, premature delivery of baby and abnormalities of the placenta.
 
5. Effects on newborns and childhood
 
Maternal smoking is associated with congenital malformations in baby such as orofacial clefts, clubfoot and atrial-septal defects. Babies born to smoking mothers have a greater risk of allergies, higher blood pressure in childhood, increased likelihood of obesity, stunted growth, poorer lung function, increased likelihood of developing asthma.
 
6. Tobacco use can also worsen other health conditions such as rheumatoid arthritis, kidney damage, eye Disease, dental disease – caries – diabetes, inflammatory bowel diseases, erectile dysfunction, etc.
 
Every year, on May 31, WHO and partners observe World No Tobacco Day (WNTD), highlighting the health and additional risks associated with tobacco use, and advocating for effective policies to reduce tobacco consumption.
