How does tobacco addiction develop? essay sample

Cigarette addiction is not merely a bad habit – it is a reasonable response of the human body to chemicals that enter its brain. However, this process is simple enough for an average person to understand. Nicotine is released into the blood as tobacco smoke fills the lungs. Within seconds, nicotine reaches our brain where it quickly binds to special receptors that release chemicals called neurotransmitters. One of them is dopamine; it causes a feeling of calmness and pleasure. Dopamine vanishes quickly, and soon receptors need more nicotine to satisfy brain receptors. They drive people smoke again and again to feel better.

Sometimes routine habits make people addicted to cigarettes. If individuals accustomed to smoking while doing some routine activities, the two actions become bound in our brain. Someone cannot drink coffee in the morning without a cigarette not because their brain is not satisfied. It is incredibly difficult to break the routine cycle if a long time has passed since the habit developed.

Stressful situations frequently trigger smoking even if a person does not usually smoke. Passing relaxation provides minutes of precious rest for people who have the weight of the whole world on their shoulders. In most cases, people get used to coping with stress with the help of alcohol and cigarettes. Affected individuals think of them even before other ways of releasing dopamine occur to them. A fulfilling meal, sweets, or scented hot bath are the most primitive but effective relaxants.
