Nicotine is addictive because it affects part of the brain that is involved in ‘rewarding behaviour’.
Nicotine has some side effects, like nausea and vomiting. Smokers have become used to these types of effects. However, non-smokers who get exposed to nicotine could experience this. People who don’t smoke should not use nicotine.
Under 18s and pregnant women
High doses of nicotine can be dangerous, especially for children.
Nicotine can affect brain development in babies, and ideally pregnant women should be smokefree and nicotine free. However, nicotine products are used to support pregnant women to stop smoking. Your doctor or local stop smoking services can give you more information.
Nicotine can also have some negative effects on brain development in adolescents.
To avoid accidental poisoning, e-liquids should be stored out of the reach of children and animals.
