The part of the brain that's responsible for decision making and impulse control is not yet fully developed during adolescence.

Young people are more likely to take risks with their health and safety, including use of nicotine and other drugs. Youth and young adults are also uniquely at risk for long-term, long-lasting effects of exposing their developing brains to nicotine.

These risks include nicotine addiction, mood disorders, and permanent lowering of impulse control. Nicotine also changes the way synapses are formed, which can harm the parts of the brain that control attention and learning.

How does the nicotine in e-cigarettes affect the brain? Until about age 25, the brain is still growing. Each time a new memory is created or a new skill is learned, stronger connections — or synapses — are built between brain cells. Young people's brains build synapses faster than adult brains. Because addiction is a form of learning, adolescents can get addicted more easily than adults.

The nicotine in e-cigarettes and other tobacco products can also prime the adolescent brain for addiction to other drugs such as cocaine. E-cigarette use among youth and young adults is strongly linked to the use of other tobacco products, such as regular cigarettes, cigars, hookah, and smokeless tobacco.
