In recent years, vaping has surged in popularity among teenagers. Marketed as a safer alternative to smoking, vaping, especially with nicotine, poses serious risks to young, developing brains. Let’s dive into how nicotine impacts the adolescent brain, affecting attention, learning, mood, and impulse control, and how these changes can influence academic performance.
The numbers: Did you know?
- Over 2.1 million middle and high school students are currently vaping (2023 National Youth Tobacco Survey).
- More than 1-in-10 young adults, ages 18-24 are vaping (CDC).
- Of youth and young adults who vape, 90% of them use flavored e-cigarettes (2023 National Youth Tobacco Survey).
- FDA has authorized only 4 flavored e-cigarettes, yet thousands of products remain on the market illegally.
The adolescent brain: Still under construction
Imagine the adolescent brain as a construction site. It’s bustling with activity, with the most significant developments happening in the prefrontal cortex—the area responsible for decision-making, impulse control, and executive functions. This brain region continues to mature well into the mid-20s, making it particularly vulnerable to external influences like nicotine.
Nicotine’s sneaky entrance
Nicotine is a powerful substance. When teens vape, nicotine swiftly enters their bloodstream and reaches the brain in seconds. It binds to receptors that release neurotransmitters like dopamine, serotonin, and norepinephrine, crucial for mood regulation, attention, and learning.
Attention and learning: The disruption
One of the most alarming effects of nicotine is its impact on attention and learning. Nicotine can alter the brain’s attention networks, making it harder for teens to focus. This can lead to classroom struggles, as sustained attention is key to learning.
Nicotine also affects the hippocampus, the brain’s memory center. Exposure during adolescence can impair the hippocampus’s ability to form new memories and retain information, directly impacting academic performance.
Mood and mental health: The rollercoaster
Nicotine’s effects on mood and mental health are significant. Teens who vape are at a higher risk of developing mood disorders like depression and anxiety. Nicotine changes the brain’s reward system, leading to mood swings and behavioral changes. The initial dopamine rush from nicotine can create a fleeting sense of pleasure, but over time, the brain craves more, leading to increased feelings of depression and anxiety.
Withdrawal symptoms from nicotine addiction can worsen these mood disorders, trapping teens in a cycle of needing nicotine to feel normal, which further impacts their mental health.
Impulse control: The struggle
Impulse control is another area where nicotine wreaks havoc. The prefrontal cortex, responsible for regulating impulses and making decisions, is still developing in teens. Nicotine exposure can disrupt this development, leading to increased impulsivity and risky behaviors, from poor decision-making in social situations to engaging in dangerous activities.
Academic performance: The fallout
The addictive nature of nicotine means that teens who vape might prioritize their habit over their studies. The time and energy spent on vaping can detract from their focus on schoolwork, leading to lower grades and decreased academic achievement.

Protecting our future: Call to action for parents and educators
Understanding the risks of vaping is crucial for parents, educators, and policymakers. Nicotine exposure during adolescence can harm attention, learning, mood, and impulse control, affecting academic success.
Steps you can take:
- Educate yourself and your child: Learn about the risks of vaping and share this information with your child. Open, honest conversations can make a big difference. Get tips at kingcounty.gov/tobacco
- Set a good example: Avoid using tobacco or vaping products yourself. Children often mimic the behaviors of their parents.
- Monitor and discuss: Monitor your child’s activities and friends. Discuss the pressures they might face and how to handle them. Visit Washington Teen Link.
- Support and resources: Provide your child with resources to quit if they are already vaping. Please encourage them to seek help from school counselors or healthcare providers. Visit the Washington State Quitline.
- Advocate for change: Get involved in community efforts to reduce youth access to vaping products. Support policies that limit the sale and marketing of these products to minors.
We can help the next generation reach their full potential by taking these steps.
