Smoking is a popular activity for many people who continue to enjoy it even though they are well aware of the health risks.
The main reason for this is nicotine addiction. Tobacco contains nicotine - a stimulant which affects both the mind and the body. It increases heart rate and breathing and causes a surge of adrenaline which gives that ‘buzz’ that smokers enjoy.
Psychologically, it causes the smoker to feel relaxed as well as stimulated which is due to the production of a chemical called Dopamine. Dopamine is released into the blood stream which causes feelings of pleasure and well being.
Your body becomes accustomed to these effects and its tolerance increases. This means that you require larger amounts or in this case, smoke more cigarettes in order to have the same effects.
This is why it is very difficult to give up smoking.
