Smoking: Even though it's known that tobacco is harmful to health and causes cancer, smokers don't quit the habit. But have you ever wondered what the real reason is for a person getting addicted to smoking?

The moment you inhale, nicotine hits your bloodstream from the lungs, reaching the brain in 7-10 seconds. Few substances act this fast, giving instant relief with one puff.

Nicotine activates nicotinic acetylcholine receptors in the brain. These act like switches, releasing chemical signals that the brain starts to see as necessary.

Nicotine triggers the release of dopamine, the 'feel-good' chemical. It reduces anxiety and relaxes the mind, which is why the craving seems to vanish after a cigarette.

With each cigarette, the brain learns that smoking means relief. The craving feels satisfied as soon as dopamine is released. This is purely a trick played by the brain.

Nicotine's effect is brief. As it fades, cravings return. Understanding this cycle is the first step to quitting. Note: Smoking is a major cause of cancer. Avoid it.
