The basic facts of smoking

Research on smoking

Smoking is very addictive, this is because tobacco contains nicotine. Nicotine effects your brain when you inhale, the effects is that it increases your heart rate and causes a surge in your hormones in your brain, these hormones are noradrenaline and dopamine. This actually gives a positive effect on your mood because it helps you to concentrate better, when you are not smoking your hormones decrease, which makes you feel anxious and irritable which makes you then crave another cigarette. Nicotine can also increase high blood pressure, this can cause vomiting, blurry vision and headaches.

A cigarette contains more than 4,000 different chemical, most of these chemicals are toxic and harmful to your body. 60 or more chemicals cause cancer.

What happens when cigarettes are taken away

When you take away a cigarette from a smoker, a number of effects take place, effects such as you feel dizzy, restless, frustrated, find difficulty in sleeping, depressed mood, irritable, eat more, decreases heart rate and lack of concentration. 

Tar

When you inhale a cigarette you also inhale tar, which sticks to your lungs. Tar contains chemicals which are called carcinogens, this helps the development of cancer cells in the body.
