Title: What is nicotine

Nicotine occurs naturally in tobacco leaves and can be extracted by heating, burning or soaking the plant

Nicotine is addictive but is it not the primary cause of smoking related diseases.

Once inhaled, it is absorbed straight into the bloodstream where it travels through the body and to the brain

Nicotine binds itself to specific receptors and triggers the release of dopamine, which boosts attention but could also cause reward-seeking behavior.

Nicotine has short-term pharmacological effects, including increased heart rate and blood pressure.

It can take anywhere between 2 and 18 hours for nicotine to leave the body.

Nicotine should never be taken by adolescents, pregnant women or people with heart conditions

The best choice any smoker can make is to quit cigarettes and nicotine use altogether.

Smoke-free alternatives are only for adult smokers who would otherwise continue smoking.

They are not risk-free and contain nicotine, which is addictive.
