An article was done on how nicotine is affecting the brain and how it can potentially lead to substance abuse. (https://physoc.onlinelibrary.wiley.com/doi/full/10.1113/JP2704920). Nicotine exposure in adolescents changes the neurochemistry and behavior due to the neuroplasticity of the brain. Nicotine increases the levels of dopamine in the brain. Dopamine is a neurotransmitter that is responsible for the feeling of pleasure. When an individual smokes there is an increase in dopamine which is how people become addicted. The nicotine also causes a release of adrenalin. Since nicotine plays a role in the brain’s judgement especially during the critical ages of adolescents, engaging in other forms of substance abuse is possible.
