【英语时差8,16】青少年吸毒（上）

（单词翻译）

What makes adolescents so vulnerable to developing addictions² to substances like nicotine³, 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 analyzed⁴ the results of many studies on this subject believe the susceptibility of adolescents to substance addiction¹ 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 fully⁵ formed in adolescence⁶. 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 impulsive⁷ and take risks.
