【英语时差8,16】青少年吸毒（上）（在线收听）

What makes adolescents so vulnerable to developing addictions to substances like nicotine, alcohol, and drugs? More vulnerable than any other age group. Is it a result of peer pressure? Of wanting to fit in? In a word, no. Socio-cultural elements do play their role. However, scientists who analyzed the results of many studies on this subject believe the susceptibility of adolescents to substance addiction also has to do with the state of development of a particular region in adolescent brains. They interpreted that the region of the brain that monitors impulse and motivation isn’t fully formed in adolescence. This area of the brain experiences a lot of activity and change during adolescence. It’s due to this brain region’s hyperactivity and quick-fire change that adolescents are more likely than children and adults to want to try out new experiences, to be impulsive and take risks.
