In this episode of Teen Talks, the focus is on how nicotine affects the teenage brain. Dr. Thiyagar explains that nicotine is the highly addictive substance found in cigarettes, cigars, and other tobacco products. Nicotine gets into the body through the lungs or mucous membranes and quickly reaches the brain, causing a rush of dopamine and other chemicals that create a feeling of pleasure and reward. The brain can become dependent on nicotine, leading to cravings and withdrawal symptoms when the level of nicotine drops. Starting nicotine use at a young age can have long-term effects on brain development and increase the risk of addiction to other substances. It is important for parents to have open communication with their teens and provide support in quitting nicotine addiction.
