Nicotine is an addictive ingredient found in tobacco products. Nicotine binds to receptors in your brain and increases the release of dopamine. Dopamine is a neurotransmitter that helps you feel pleasure. Not having nicotine can also change your mood. Some people who quit smoking become depressed. This may be because the levels of dopamine in their brain is affected by the lack of nicotine.

Nicotine remains in your body for a short period of time. Not having nicotine can cause cravings for it. This can make it hard to quit tobacco use. There are a few things that can help you quit tobacco use. These are:
