Yes. Passive smoking (secondhand smoke) can negatively affect a child’s brain development. When children inhale smoke from cigarettes, they are exposed to harmful chemicals like nicotine, carbon monoxide, and toxic particles. These substances can interfere with the developing brain, increasing the risk of problems with attention, learning, memory, and behavior.
Studies have linked secondhand smoke exposure in children to a higher likelihood of neurobehavioral disorders such as ADHD, learning difficulties, and emotional regulation issues. Younger children and infants are especially vulnerable because their brains are still rapidly developing.
Protecting children from smoke—at home, in cars, and in public spaces—is essential for their healthy brain growth and overall well-being.
