It comes as no surprise that smoking is harmful to our health, but what about its effects on our brain?

First and foremost, nicotine is habit-forming.

As a result, the addicted brain of a cigarette smoker does not function properly as nicotine triggers various chemical reactions inside the brain such as the feelings of euphoria and pleasure as well as other sensations that are always short-term.

Over some time, a cigarette smoker will experience withdrawal symptoms which are revealed in a depressed state of mind and lack of confidence.

As the levels of nicotine drop in the blood system, smokers start feeling nervous, and this discomfort provokes them to use another cigarette and keep smoking.

Nicotine affects the brain in only a few seconds after inhaling the smoke.

It provokes the release of adrenaline which is revealed in an increased heartbeat, elevated blood pressure and distorted blood flow to the smoker’s heart.

Besides, nicotine distorts the release of insulin and, therefore, increases the level of sugar in the blood.

As a result, smokers may feel a reduced feeling of hunger which is always temporary.

Such an essential hormone as dopamine is also simulated when you use nicotine.

This explains why smokers feel euphoria and satisfaction with life as soon as they puff a cigarette.

As such, nicotine violates many vital processes in the brain and body, which is aggravated by an increased level of chemicals contained in cigarettes.
