Cigarettes have nicotine. When anyone, it may be a teenager or an adult, puffs into a cigarette, a considerable amount of nicotine finds itself inside the lungs and into the body through the blood.
Nicotine is a powerful stimulant, but it has tremendous withdrawal symptoms too. Those who want to give up smoking are faced with a craving for a puff when they spend a lot of time without a cigarette.
These symptoms can be specifically hard on a teenager, who is not sure of the elements of lifestyle he or she should embrace at that stage and those that should not be. The allure and excitement of a cigarette is hard to control, but one has to go through a lot of unpleasant feelings when made to live for a long time without cigarettes.
There is an immense amount of pressure from one's peers to confirm to the norms of smoking, and the teenager finds himself or herself torn to pieces between the two ends.
The problem is that nicotine has the power to change the balance of chemicals in the brain. This in turn alters the mood of the person, and, of course, the concentration also waivers. The very uncertainty created by nicotine in cigarettes is what makes smokers hooked to it.
Nicotine is a stimulant that relieves anxiety and stress in individuals. A typical feeling of pleasure is what replaces the stress and anxiety. This is what makes cigarettes in demand among teenagers.
With hormones ravaging around their bodies, and causing changes in mood, nicotine is what regulates the mood, and teenagers become hooked to cigarettes.
