Meaning of Addiction
According to psychologists, state of being dependent on something is addiction. It could either be psychological or physical, but whatever it is, addiction insinuates a neurotic or persistent urge to repeat everything that caused the person’s dependency on something.
Normally, the formation of cravings or desire triggers the onset of addiction. On answering these cravings, another craving would rise but this time with more intensity than the first one. As this cycle will go on and on and without knowing it, you are already an addict.
Young Women Smoking For All the Wrong Reasons
Nicotine dependency is the most common form of drug addiction and causes more deaths and disease than all other addictions combined. And when it comes to smoking addiction, cigarette smoking is the one most likely to take hold during adolescence. So with all those people smoking, there have to be other “reasons” for it beyond being a coping mechanism.
And there are – particularly if you ask young women. Some start smoking because it’s still considered cool in certain circles. Peer pressure is really powerful, and if the popular crowd says, “If you light up, you’re cool with us,” that can be hard to resist.
Another draw for girls who start smoking during puberty is it seems to help with hormonal changes that cause mood fluctuations. Nicotine works like other drugs when it comes to anger, depression and mood swings. It goes to the pleasure center of the brain and says, “Chill out! Everything is going to be OK.”
Many people are asking whether cigarette manufacturers are including marijuana in the cigarette to trigger smoking addiction to people. Of course, the productivity of the manufacturers will grow, if people get addicted to it.
It can be true that the cigarette manufacturers are adding marijuana but it’s hard to believe anything because there are no such reports yet as to whether manufacturers really adding marijuana as an smoking addition material.
However, there are elements in cigarette that really instigates smoking addiction, and that is nicotine. In fact, nicotine is regarded as one of the toughest stimulants ever identified. So, nicotine is s one of the most common factor that leads to smoking addiction.
Basically the nicotine level is directly infused into the brain, when a person smokes. This helps the smokers to have some relief from tension. The problem is that the anxiety sets back in with greater intensity after several tension-free minutes, and demands for more doses of stress-relievers i.e. nicotine.
In this way the smoking addiction starts. People who smoke as a way to release tension are already addicted to smoking. They slowly increase the number of cigarettes. This shows the person’s dependency on the cigarette already. This can be traced to where the smoking addiction starts.

Once lit, a cigarette reaches a temperature of nearly 2,000 degrees Fahrenheit. This high heat helps release thousands of chemical compounds, including poisons like carbon monoxide and hydrogen cyanide, at least 43 carcinogens, and numerous mutagens. All of these are drawn into the body when a smoker inhales.
Dangers Of Smoking With Nicotine
One of the main dangers of smoking is due to Nicotine. Nicotine is found naturally in tobacco. It has no odor and no color. It is, however, both physically and psychologically addictive, and it causes those who use it to want to smoke one cigarette after another.
Nicotine enters the body as tiny droplets resting on particles of tar in cigarette smoke. Inhaled into the lungs, the drug passes quickly into the bloodstream, reaching the brain within about 10 seconds. In another 5 to 10 seconds the nicotine has spread to all parts of the body.
The nicotine raises both the heart rate and blood pressure. The smoker quickly feels more alert and relaxed. In less than 30 minutes, however, about half of the nicotine has left the bloodstream, and the smoker starts feeling less alert, more edgy.
So he or she reaches for another cigarette to get a new “hit” of nicotine. Over time, the smoker starts needing more cigarettes throughout the day to satisfy the craving.
Dangers Of Smoking With Tar
There are other dangers of smoking as well. The tar from tobacco smoke starts to accumulate on the bronchial tubes leading to the lungs. The hot smoke burns the tiny hairlike projections (called cilia) that trap harmful particles before they enter the lungs.
One more of the dangers of smoking are Carbon monoxide. Smoking also increases the level of carbon monoxide in the lungs. This poisonous gas is quickly absorbed into the blood, reducing its capacity to carry oxygen.
As a result, the smoker has to exert more physical effort to attain a given task than does a nonsmoker. The heart in particular must work harder, particularly during rigorous exercise. Increased levels of carbon monoxide in the blood can impair vision, perception of time, and coordination.
