Quizplus · Accepted Answer

Nicotine stimulates receptors in the brain that release dopamine, a neurotransmitter associated with pleasure and reward. This is similar to the feeling of achieving a rewarding goal, which is why nicotine can be so addictive.  Nicotine mimics natural chemicals in the brain that make us feel good when we do something right, a mechanism that aids survival. When nicotine causes these receptors to respond, it feels to the smoker as if smoking is the right thing to do.
