How Nicotine Affects Your Brain [upbeat music playing]
Within a few seconds of taking a puff, the chemical nicotine reaches your brain. Nicotine releases chemical messengers called neurotransmitters like dopamine, which acts in the reward center of the brain. Other neurotransmitters that act on different parts of your brain can enhance concentration, memory, and mood. That's why when you first start to vape or smoke, it can feel good.
That's how it starts to hook you. The more you vape, the more tolerance you build and the more nicotine you need to get the same feeling. That's because your brain actually changes. Now there are more receptors in your brain that require more nicotine to get the feel good chemical messengers.
So you do it more often or use vapes with higher nicotine levels. After using nicotine regularly for weeks, if you try to stop, you can feel nauseated, anxious, irritable, or have headaches. Then you have to vape more just to feel normal again, which makes it really hard to stop. Even if you want to.

Description of video imagery
Title: How Nicotine Affects Your Brain
A person's head appears. Circular Ns, representing nicotine, stream into the brain. The figure puffs on an e-cigarette, and Ns spread throughout the brain. Blue circles emit from nicotine molecules into the brain. A dopamine starburst appears. Icons representing concentration, memory, mood appear. A blue figure does a happy dance. Rs representing receptors absorb multiple Ns for nicotine. The figure vapes while nicotine floods the brain. Weeks pass on the calendar. The figure shows nausea, irritability, headache, and suffering. The screen fills with nine head figures vaping. The brain appears on screen with nicotine molecules dissipating. Helpful resources for quitting nicotine appear. A link to the project website and references are provided.
