Everybody who smokes these days is at least vaguely aware of the damage that cigarettes do to their body. Ignorance is no longer an excuse. That is why they have to put the warning labels on the packs. If you smoke it is because, at least initially, it made you feel good. It gave you a 'buzz'. Cigarettes can heighten awareness and increase the amount of adrenaline in the body. They can calm the nerves, lift your mood, and give you a sense of improved judgement.When you smoke a cigarette your brain receives a rush of nicotine. The tar that you inhale carries nicotine to the lungs where it is absorbed. The blood takes the nicotine from the lungs to the heart which pumps it through the arteries to the rest of the body. The process only takes about 8 seconds from when you inhale. The nicotine stimulates the secretion of neurotransmitters in the brain that appear to enhance your judgement and awareness. Nicotine can improve your mood by increasing your dopamine levels. It raises your blood pressure and heart rate while increasing the levels of various hormones, including adrenaline. Nicotine lowers your skin temperature and affects your muscle tone. Many smokers get so used to the intake of nicotine that they experience physiological withdrawal if they have to do without it. They have a dependence on nicotine that makes it very difficult to give up cigarettes. They also have a behavioural tie to smoking that makes them automatically reach for a cigarette in certain social situations. This compulsive behaviour is what makes the body's dependence on nicotine more akin to an addiction. This is why it is so difficult to quit smoking for good.So there you have it.
