Cigarettes contain something like 600 chemicals and the smoke contains an unbelievable 7,000 chemicals of which, about 69, are carcinogenic and others poisonous. As far as veining the smoker of the cigarette the villain is Nicotine. It is Nicotine that drags one to smoking. It reaches the brain in a matter of seconds and enslaves the brain so to say. It increases the energy level and makes one feel very active and enthusiastic. However, this feeling is very transient and the energy levels drop off in quick time leaving one desperate for more. Succumbing to this makes one a cigarette addict in no time. The power of addiction is very strong and breaking it is one of the hardest actions. Almost everyone makes quite a few attempts before finally succeeding. Physical withdrawal can affect the cognitive functions, causes anxiety, irritated and often depressed. Withdrawals can lead to sleep disruption and headaches too. A knowledge of the ill health effects of smoking cigarettes is found wanting as a motivator for quitting. Repeated nudging by family members, health professionals, close friend and associates, especially those who have succeeded in quit smoking is what propels the smoker to resolve to give up the cigarette.
