Smoking addiction is the reason why tobacco has become what it is today - a world wide problem. People are addicted to smoking because of a dependence substance found in tobacco called nicotine.
It's amazing when you consider the effects of nicotine. In fact tobacco plants produce nicotine in order to protect themselves aganist wild animals in the ecosystem. As far as the plants are concerned nicotine is a poison. This is why it is possible to suffer from nicotine poisoning.
Nicotine makes it impossible for those who so desperately wish to give up smokingto actually quit smoking dispite of all the known dangers of smoking. Cigarette addiction is as a result of the nicotine in cigarettes that travels to the brain within 10 to 15 seconds of a puff.
Nicotine addiction symptoms would include an irrestible desire to smoke time and again. It would also extend to the manifestation of severe nicotine withdrawal symptoms as soon as one attempts to quit. A clear warning from the body that it won't acccept that. This would include severe headaches, shivering, confusion and irritability amongst many others.
Once the nicotine reaches your head, it crosses what is known as the blood-brain barrier and enters the brain. It attaches itself to brain receptors responsible for pleasure and stimulates a whole chain reaction that results in temporary pleasure.
Throught this repeated process, the brain learns to depend on this cycle over and over again and can hardly do without it. This becomes smoking addiction.
This is the reason millions have to smoke every 30 to 45 minutes through-out the day in order to feed and sustain this dependency.
Unfortunately, nicotine does not stay long in the body. For this reason it has to be constantly replenished in the brain of a smoker. Many people who smoke have endless reasons to quit smoking.
Many more even read and research on how to give up smoking. Without an understanding of what is happening to one's body when you smoke it makes the task of stopping smoking even more unbearable.
As a result of people failing to quit smoking due to tobacco addiction eventualy smoking diseases such as cancer, heart disease and others will set it.
Smoking statistics show that there are millions of people worldwide who are addicted to smoking. As many as 300 million in China alone. This number increases daily especialy in the developing countries such as India, China and parts of Africa.
Teenage smoking is on the raise too because of nicotine addiction. What often begins as fun and harmless often and always becomes a runaway monkey on someone's back for decades to follow. When you attempt to stop smoking health professionals will not hide this to you that giving up smoking is hard. Nicotine is the dreadful culprit.
The FDA in the United States has since classified smoking addiction as a disease. There are new and advancing treatment researches in the area of nicotine addiction. These are trying to find ways to stop nicotine from reaching the brain.
The concept involves blotting nicotine molecules making them too big to cross the blood-brain barrier. If successful, as it is currently indicating, even if you smoke after being vaccinated by this nicotine vaccine you will not be addicted.
Many questions will however arise. Would smoking still be appealing to smokers without brain stimulation leading to pleasure? One thing for certain is that those who smoke and are desparate to quit will have a renewed hope as the vaccine will also destroy nicotine withdrawal symptoms.
Indeed, understanding tobacco addiction lays in understanding the relationship between nicotine and the brain.
