Smoking can harm teen brains

Topics: Health Issues

Keep smoking teens, you're frying your brain.

In an experiment performed in England years ago, the effects of nicotine were related to that of amphetamines and cocaine. Both amphetamines and cocaine release dopamine in the nucleus accumbens and increase locomotor activity. The nicotene you are sucking into your body is affecting your learning, memory, attention, mood, and yes, as you age, your sex life.

"Researchers at Yale University tested working memory, the form used when keeping information in mind and manipulating it, among 41 adolescent smokers and 32 non-smokers. They also evaluated the teens' verbal learning and memory, attention, mood, symptoms of nicotine withdrawal and tobacco cravings. Both groups were similar in age, gender and education.

They found the teen smokers had impairments in the accuracy of their working memory, which contrasts with studies showing adult smokers actually have the same focused, sustained and selective attention, and improved working memory, compared with non-smoking adults."
