Teenagers who start smoking by the age of 14 may be at risk of having less grey matter in a specific section of their brain, according to a recent study conducted by the universities of Cambridge and Warwick in Britain, along with Fudan University in China. The study, which was published in the scientific journal Nature Communications, suggests that adolescents with reduced grey matter in this brain region may experience lower cognitive function and be more prone to engaging in rule-breaking behavior and developing bad habits such as smoking.
Grey matter, responsible for processing information in the brain, reaches its peak growth and development during the teenage years. The researchers discovered that teenage smokers also had less grey matter in the right part of the same brain region. This area, known as the right frontal lobe, is associated with seeking sensations, and the shrinkage that occurs in smokers could potentially lead to addiction and impact the way adolescents seek pleasure.
The scientists involved in the study hope that these findings can aid in the identification and prevention of teenagers who are at risk of starting smoking before they become addicted. “Smoking is perhaps the most common addictive behavior in the world, and a leading cause of adult mortality. The initiation of a smoking habit is most likely to occur during adolescence. Any way of detecting an increased chance of this, so we can target interventions, could help save millions of lives,” stated Cambridge University Professor Trevor Robbins, co-author of the study.
According to the Centers for Disease Control and Prevention (CDC), in the United States alone, approximately 1,600 young people try their first cigarette before the age of 18 every day. Furthermore, nearly half a million Americans die prematurely each year as a result of smoking or exposure to secondhand smoke. These statistics emphasize the urgency of addressing smoking in adolescence and the importance of developing strategies to prevent young people from starting smoking.
The study’s findings highlight the detrimental effects of smoking on teenagers’ brain development and cognitive abilities. By understanding the connection between smoking and reduced grey matter in the brain’s frontal lobe, researchers hope to pioneer interventions that can help safeguard adolescents from the many dangers associated with smoking.
