Smoking is harmful to your health
When your parents were young, people could buy cigarettes and smoke virtually anywhere, even in hospitals! Cigarette advertising was everywhere. Currently, we are more aware of what smoking is bad for our health. Cigarettes are restricted or prohibited in virtually all public places and companies that manufacture cigarettes and can not do propaganda on buses or trains, road signs, television and in many magazines. Almost everyone knows that smoking causes cancer, emphysema and heart disease, that can shorten your life by 10 years or more and that the habit can cost a smoker thousands of dollars annually.
So why do people still smoke? The answer is very simple: it is an addiction. Once you start is very difficult to quit smoking is a habit hard to break because the snuff contains nicotine, which is highly addictive. As with heroin or other addictive drugs, the body and mind so quickly get used to the nicotine that the person needs to consume to feel good. Almost no smoker begins to smoke as adults. Statistics show that approximately 9 out of 10 smokers start before 18 years of age. Some teens who smoke say they start because they think it makes them look bigger (and it is true, as long as you want to have yellow teeth and wrinkles). Others smoke because they believe it helps them relax (but not, in fact, the heart beats faster while a person smokes).
Some start smoking as a way to feel rebellious or to differentiate (which works if you want your friends have to wait somewhere else while you smoke). Others start because their friends smoke, or simply because they have something to do. Some people, especially girls, start smoking because they think it can control your weight. The diseases that smoking can cause, such as lung diseases or cancer, do cause weight loss, but not a very good way to lose weight! Another of the reasons why people start smoking is because members of your family makes. Most adults who started smoking in their teens never thought they would become addicted. That’s why people say they would have been much easier not to start smoking. The advertisements of cigarettes from the time when your parents were young convinced many of them that smoking was glamorous, striking or fascinating, although in reality is something repugnant-smelling, expensive and unhealthy.
The cigarette ads in the 1940s even showed doctors who recommended the cigarette as a way to relax! The cigarette ads still show smokers as attractive and modern, sophisticated and elegant, or rebellious and cool. The good news is that now these ads are not so visible and are less effective than before: in the same way that doctors are more sensible about cigarettes today than in the previous generation, teenagers are more aware of how manipulative they can be advertisements. The government has also passed laws that limit where and how you can advertise tobacco companies to help children avoid the vice of smoking.
How did the cigarette your health There are no physical reasons to start smoking: the body does not need snuff in the way it needs food, water, sleep and exercise. In fact, many of the chemicals in cigarettes, like nicotine and cyanide, are actually poisons that can kill in high enough doses. The body is smart and defended when it is being poisoned.

Difficult to leave the snuff if the mother smoked during pregnancy
It is known that prenatal exposure to nicotine alters brain areas critical for memory, learning and sense of reward. Scientists at the Center for Research on smoking cessation and nicotine-dependent Duke University have discovered that these alterations may program the brain to suffer a relapse of addiction to nicotine.Rodents exposed to nicotine before birth self-administered more of the drug after periods of abstinence than those who had not been exposed.
The study suggests that pregnant women should quit smoking to keep their unborn children are exposed to nicotine and also should do so without the use of nicotine products such as certain patches or gum, according to researchers, also pose a risk to the baby.
“Smoking during pregnancy can harm the baby go far beyond a premature delivery or low birth weight,” says lead study investigator Edward Levin, a professor of biological psychiatry.”In addition, causes changes in the baby’s brain development can affect you for life.”
Levin’s team exposed pregnant rats to nicotine.When their offspring they became teenagers, were allowed to self-administer nicotine whenever you want.To self-administer the drug, the rats pressed a lever that released a dose of nicotine intravenously. Each push the lever was roughly equivalent to one puff of a cigarette.
The researchers studied two groups of rats: those that had been exposed to nicotine during pregnancy and those who had not been. Both groups of rats consumed the same rate of nicotine, about 10 puffs per session. After 4 weeks, the researchers forced the rats to experience withdrawal symptoms for a week in which they had no access to nicotine.
When scientists restored access to nicotine, they witnessed a noticeable difference in the rate at which rats resumed the habit. Those who had been exposed during pregnancy, taking almost twice as puffs of nicotine than others.
