It’s finally time to uncover the answer to the question: Why do people smoke? If you have ever had cigarette smoke blown into your face on a windy day, or if you have ever seen a commercial with a lung cancer patient speaking through a mechanical voice box, you have probably asked yourself the question:

Why do people smoke? Why would they subject themselves to something like that? Unfortunately, even though there are dangers to smoking, a lot of people still consider it their guilty pleasure. Their bad habit they just cannot seem to quit.

Why Do People Smoke?

Most people smoke as a way to cope with their stress. The nicotine calms them down because it is a mood altering drug that impacts the brain. It triggers the release of dopamine, which brings pleasure and relaxation.Smoking can also reduce appetite. If someone wants to lose weight, they can kill their cravings by putting a cigarette into their mouth instead of putting food into their mouth.

Peer pressure can also trigger a smoking addiction. If someone is in a group of friends who are all smokers and keeps getting offered cigarettes, they might feel tempted and eventually agree to the offer. They might also feel like smoking could bring them closer with their friends and coworkers because it gives them a chance to take smoke breaks together, it gives them a chance to socialize……Continue reading….

Smoking is one of the leading preventable causes of deaths globally and is the cause of over 8 million deaths annually, 1.2 million of which are non-smokers who die due to second-hand smoke.In the United States, about 500,000 deaths per year are attributed to smoking-related diseases and a recent study estimated that as much as 1/3 of China’s male population will have significantly shortened life-spans due to smoking.

Male and female smokers lose an average of 13.2 and 14.5 years of life, respectively. At least half of all lifelong smokers die earlier as a result of smoking. The risk of dying from lung cancer before age 85 is 22.1% for a male smoker and 11.9% for a female current smoker, in the absence of competing causes of death. The corresponding estimates for lifelong nonsmokers are a 1.1% probability of dying from lung cancer before age 85 for a man of European descent, and a 0.8% probability for a woman.

Smoking just one cigarette a day results in a risk of coronary heart disease that is halfway between that of a heavy smoker and a non-smoker.The non-linear dose–response relationship may be explained by smoking’s effect on platelet aggregation. Among the diseases that can be caused by smoking are vascular stenosis, lung cancer,heart attacks and chronic obstructive pulmonary disease (COPD). Smoking during pregnancy may cause ADHD to a fetus.

Smoking is a risk factor strongly associated with periodontitis and tooth loss.The effects of smoking on periodontal tissues depend on the number of cigarettes smoked daily and the duration of the habit. A study showed that smokers had 2.7 times and former smokers 2.3 times greater probabilities to have established periodontal disease than non‐smokers, independent of age, sex and plaque index, however, the effect of tobacco on periodontal tissues seems to be more pronounced in men than in women.

Studies have found that smokers had greater odds for more severe dental bone loss compared to non‐smokers , also, people who smoke and drink alcohol heavily have much higher risk of developing oral cancer (mouth and lip) compared with people who do neither. Smoking can also cause milanosis in the mouth.

Smoking has been also associated with oral conditions including dental caries, dental implant failures, premalignant lesions, and cancer. Smoking can affect the immune-inflammatory processes which may increase the susceptibility to infections; it can alter the oral mycobiota and facilitate colonization of the oral cavity with fungi and pathogenic molds.

Many governments are trying to deter people from smoking with anti-smoking campaigns in mass media stressing the harmful long-term effects of smoking. Passive smoking, or secondhand smoking, which affects people in the immediate vicinity of smokers, is a major reason for the enforcement of smoking bans. These are laws enforced to stop individuals from smoking in indoor public places, such as bars, pubs and restaurants, thus reducing nonsmokers’ exposure to secondhand smoke.

A common concern among legislators is to discourage smoking among minors and many states have passed laws against selling tobacco products to underage customers (establishing a smoking age). Many developing countries have not adopted anti-smoking policies, leading some to call for anti-smoking campaigns and further education to explain the negative effects of ETS (Environmental Tobacco Smoke) in developing countries.Tobacco advertising is also sometimes regulated to make smoking less appealing.

Despite the many bans, European countries still hold 18 of the top 20 spots, and according to the ERC, a market research company, the heaviest smokers are from Greece, averaging 3,000 cigarettes per person in 2007. Rates of smoking have leveled off or declined in the developed world but continue to rise in developing countries. Smoking rates in the United States have dropped by half from 1965 to 2006, falling from 42% to 20.8% in adults.
