The culture of smoking originated in South America and Mesoamerica in 5000 BC by people who followed Shamanism. It later spread to parts of Europe in the 16th century by the introduction of tobacco trading and other hallucinogenic substances. Following the modernization, the increase in cigarette manufacturing and its availability has led to the spread of smoking practice all over the world.

Smoking is a common practice among medical students. Students consider smoking as a stress-relieving aid due to the high-pressure environment causing psychological pressure. Other reasons for habit initiation could be the influence of friends who are involved in smoking.

Secondhand smoking refers to the smoke of tobacco which is breathed in by the general people passively who are in close contact with a smoking person. Passive smoking, involuntary smoking, and environmental tobacco smoke are some of the forms of smoking that refer to secondhand smoking. A nonsmoker person is exposed to the same levels of the toxins and chemicals like nicotine as a smoker by inhaling secondhand smoke.
Children are most vulnerable to exposure to secondhand smoke that also increases their health issues. This smoke is also harmful to lactating mothers as these chemicals may reach breast milk.
There are more than 250 chemicals identified that are harmful to health which is inhaled in secondhand smoke. Some of these chemicals can also lead to cancer. The U.S. Environmental Protection Agency (EPA) has classified these cancer chemicals as human carcinogens. These chemicals can also induce cardiovascular and respiratory disorders that may lead to serious health conditions. Arsenic, Vinyl chloride, Cadmium, ethylene oxide, Benzene are some of the most dangerous substances involved.
Mental health issues associated with substance abuse
Long-term use of certain drugs can cause changes in the brain and induce conditions like depression, anxiety, hallucinations, aggression, and other concerns. Common substances include cocaine, ketamine, marijuana, MDMA, steroids, methamphetamine, LSD, inhalants, etc. Addiction to these inductive medications or drugs doubles the chances of mental illness.
Why doctors want their patients to recover
Quitting a smoking habit has multiple health benefits for both men and women. It helps in improving health issues in people of all ages. People who stop smoking before the age of 50 have a half-time lower risk of death in the next 15 years than people who choose to smoke.
There are various risk factors associated with smoking. The occurrence of heart diseases like coronary artery disease, chances of stroke, blood clots, and arterial blockages are higher in smokers.
Respiratory problems like lung diseases, chronic obstructive pulmonary disease, emphysema, chronic bronchitis, and increased risk of lung cancer are more common in the smoking population than in nonsmokers. It becomes more difficult to treat if the patient is a smoker. The risk for premature death also increases. Even after one of these cancers has been diagnosed, stopping smoking decreases the risk of developing second cancer and may increase the chances of surviving the first.
Smokers are at high risk of developing a cataract, retina damage, eye inflammation, and blindness as compared to non-smokers.
Smoking can negatively impact a woman's pregnancy. A pregnant woman can transfer harmful toxins during smoking to the placenta and impact prenatal growth. This may also cause problems in the newborn like crossed eyes (strabismus), infant eye disease, and other eye problems. The risk of impotence, stillbirth, infant anomalies, low birth weight of newborns is some of the factors associated with smoking.
Dental infections and gum inflammations are also associated with smoking. In general, smokers have reduced immunity and healing capacity which leads to the development of other infections and increased risk of cancers.
Tobacco use has a greater effect on the health of people in rural areas than it does in urban and metropolitan areas, owing to socioeconomic factors, history, policies, and a lack of adequate healthcare. Lung cancer rates are 18–20 percent higher in rural areas than in urban areas.
Stopping smoking not just benefits the health but also helps in strengthening the relationship with family and friends by improving the quality time, since secondhand cigarette smoke is related to a variety of serious health problems. It also enhances the socioeconomic factors and behavioral issues.
Success/failure rate of smoking
The process of discontinuing tobacco smoking is called smoking cessation. Since the chemical present in tobacco called nicotine is an addictive substance, it causes dependence, and hence, its withdrawal is a difficult process.
The British Doctors' Study was a prospective cohort study which ran from 1951 to 2001, and in 1956 provided convincing statistical proof that tobacco smoking increased the risk of lung cancer.
Survival from age 35 of non-smokers, cigarette smokers and ex-smokers who stopped smoking between 25 and 34 years old. The ex-smokers line follows closely to the non-smokers line.
In 2002, The Ministry of Health and Family Welfare of the Government of India developed 13 tobacco cessation clinics (TCCs) with the help of the World Health Organization India Country Office. Later 19 more offices were opened to provide tobacco cessation interventions. These clinics aimed to develop smoking cessation methods for smokers.
As a result, 69 percent of users received only therapeutic intervention, while the remaining 31% received both behavioral intervention and pharmacotherapy.
On the other hand, as per surveys, almost 50% smokers failed to quit their smoking habit. A global survey of 17,000 participants from 13 countries concluded that smokers are sacrificing their physical and economic well-being to smoke, even though many of them have the desire to quit.
According to the WHO Global Action Plan for the Prevention and Control of Noncommunicable Diseases 2013–2020, countries should aim for a 30 percent reduction in tobacco use prevalence by 2025, using 2010 as a benchmark. This corresponds to a maximum cumulative tobacco use prevalence rate of 19.1 percent among people aged 15 and up, 30.2 percent among men, and 8.0 percent among women.
