Smoking, Much Bad and Little Good for Health

Tobacco smoke is enormously harmful to your health. There’s no safe way to smoke. Replacing your cigarette with a cigar, pipe, or hookah won’t help you avoid the health risks associated with tobacco products.  According to the National Cancer Institute, cigars have a higher level of carcinogens, toxins, and tar than cigarettes. When using a hookah pipe, you’re likely to inhale more smoke than you would from a cigarette. Hookah smoke has many toxic compounds and exposes you to more carbon monoxide than cigarettes do.  In the United States, the mortality rate for smokers is three times that of people who never smoked, according to the Centers for Disease Control and Prevention. It’s one of the leading causes of preventable death.

Smoking More Bad …

1.Cause cancer

Smoking leads to cancer of the lung, nose, mouth, larynx (voice box), trachea, esophagus, stomach, pancreas, kidneys, bladder, cervix, bone marrow and blood. When you smoke, the entire process – right from when you light up your cigarette to when you exhale – leads to several drastic and disastrous effects in the body. Out of the 41,000 chemicals in cigarettes, a large percentage are known to be carcinogenic (cancer causing). These chemicals combined with the heat of the smoke leads to mutations in your cells causing them to multiply in an uncontrolled manner, leading to cancer.

2.Rinkles and premature ageing

Smoking leads to the appearance of fine lines(especially around the eyes and lips), age spots, puffy eyes, dull, dry and lifeless skin. The chemicals present in cigarettes cause the fine capillaries under your skin to contract and constricts the blood flow to your skin. This lack of blood and fresh oxygen causes your skin to look dull and lifeless. So much so that the habit leads to permanent damage to connective fibers like elastin and collagen – leading to the formation of permanent lines and wrinkles.

3.Sexuality and Reproductive System

Restricted blood flow can affect a man’s ability to get an erection All these factors put together lead to the lack of proper function of the male reproductive system, causing premature ejaculation. Apart from that, research conducted at the University of Arizona found that smoking directly impacts a man’s sexual desire, stamina and overall interest in sex. Both men and women who smoke may have difficulty achieving orgasm and are at higher risk of infertility. Women who smoke may experience menopause at an earlier age than nonsmoking women. Smoking increases a woman’s risk of cervical cancer.

4.Bad breath

This not only relates to the commonly known ‘smoker’s breath’, but in some cases may lead to severe and persistent bad breath. Apart from killing off the good bacteria in your mouth, smoking is also known to cause problems with digestion, throat infections and build up of chemicals within the oral cavity . Not only does smoking cause conditions like oral thrush but also leads to a condition called ‘smoker’s palate’ (where the roof of the mouth is covered with cigarette residue, leading to formation of small red spots on the palate) which is one of the main reasons for bad breath.

5.Stains your teeth

Cigarettes contain tar, a chemical that coats your teeth lending them a yellowish tinge. This tar is difficult to clean with brushing and usually forms permanent stains on a smoker’s teeth. Apart from that the habit also kills the good bacteria in your mouth, increases the amount of saliva secreted and causes a higher amount of tartar formation on your teeth.

6.Central Nervous System

One of the ingredients in tobacco is a mood-altering drug called nicotine. Nicotine reaches your brain in mere seconds. It’s a central nervous system stimulant, so it makes you feel more energized for a little while. As that effect subsides, you feel tired and crave more.  Smoking increases risk of macular degeneration, cataracts, and poor eyesight. It can also weaken your sense of taste and sense of smell, so food may become less enjoyable. Your body has a stress hormone called corticosterone, which lowers the effects of nicotine. If you’re under a lot of stress, you’ll need more nicotine to get the same effect. Physical withdrawal from smoking can impair your cognitive functioning and make you feel anxious, irritated, and depressed.

7.Weakens your heart,

According to the CDC (Center for Disease Control), a smoker is two to four times likelier to suffer from coronary artery disease and stroke than a non-smoker. Moreover, people who smoke have a 25 times greater risk of suffering from lung cancer. The chemicals present in cigarette smoke affects the entire composition of your blood; making it thicker and more prone to formation of blood clots. Apart from that it also causes the constriction of your blood vessels, increases your blood pressure , and leads to the formation of plaque – increasing your chances of suffering from cardiovascular and heart disease.

8.Lowering your stamina and lung capacity

Cigarettes have a large number of chemicals which leave a considerable amounts of residue in your lungs, airways and your entire body in general. All this residue ends up clogging your lungs leading to  breathing problems and lowered lung function. This lack of fresh oxygen and blood to various parts of your body causes fatigue and breathlessness. Research has shown that smoking can lead to COPD (Chronic Obstructive Pulmonary Disease), emphysema, chronic bronchitis, pneumonia, lung infections, asthma and increases one’s risk of suffering from TB (tuberculosis).

Smoking Little Good …

1.Lowers risk of Parkinson’s disease

Numerous studies have identified the uncanny inverse relationship between smoking and Parkinson’s disease. Long-term smokers are somehow protected against Parkinson’s, and it’s not because smokers die of other things earlier.
Harvard researchers were among the first to provide convincing evidence that smokers were less likely to develop Parkinson’s. In a study published in Neurology in March 2007, these researchers found the protective effect wanes after smokers quit.

2.Lowers risk of obesity

Smoking — and, in particular, the nicotine in tobacco smoke — is an appetite suppressant. The relationship between smoking and weight control is complex: Nicotine itself acts as both a stimulant and appetite suppressant; and the act of smoking triggers behavior modification that prompts smokers to snack less. Smoking also might make food less tasty for some smokers, further curbing appetite. As an appetite suppressant, nicotine appears to act on a part of the brain called the hypothalamus.
No respectable doctor would recommend smoking for weight control, given the toxic baggage accompanying cigarettes. This recent Yale study, however, does offer an inkling of hope for a safe diet drug to help obese people control their appetites.

3.Lowers risk of knee surgery

While smokers might go broke buying a pack of cigarettes, they can at least save money by avoiding knee-replacement surgery. Surprising results from a new study have revealed that men who smoke had less risk of undergoing total joint replacement surgery than those who never smoked.
The study, from the University of Adelaide in Australia, appears in the July issue of the journal Arthritis & Rheumatism. What could be the connection? Knee-replacement surgery was more common among joggers and the obese; smokers rarely jog, and they are less likely to be morbidly obese.

4.Lowers risk of death after  heart attacks

Compared with non-smokers, smokers who have had heart attacks seem to have lower mortality rates and more favorable responses to two kinds of therapy to remove plaque from their arteries: fibrinolytic therapy, which is basically medication; and angioplasty, which removes the plaque by inserting balloons or stents into the arteries.
The reason why smokers have heart attacks is that smoke scars the arteries, allowing fat and plaque to build up in the first place. So, one theory as to why smokers do better than non-smokers after such therapies is that they are younger, experiencing their first heart attack approximately 10 years before the non-smoker.
