Putting your quit plan into action

Nicotine addiction

Nicotine, a naturally occurring substance in tobacco, affects the brain by producing a pleasurable sensation without changing behaviour. Much like hard drugs, however, nicotine leads to addiction and physical dependence.

How addiction happens

Nicotine stimulates the brain within 10 seconds of every drag.

The brain reacts to this stimulation by producing substances known as” endorphins,” which make you feel good. One of these substances, dopamine, is primarily responsible for the enjoyable sense of relaxation you get from smoking. The brain actually becomes addicted to these substances, not to nicotine itself.

Your brain normally produces these “feel-good” substances on its own, when you do something you enjoy or when you are having a good time, for example.

When you quit smoking, your brain has to relearn to produce and regulate endorphins without the use of nicotine in order for you to avoid experiencing withdrawal.
