　　Smoke Gets in Your Mind
　　1. Lung cancer(肺癌), hypertension(高血压), heart disease, birth defects(先天性缺陷)—we are all too familiar with the dangers of smoking. But add to that list a frightening new concern. Mental illness(精神疾病). According to some controversial(有争议的) new findings, if smoking does not kill you, it may, quite litter, drive you to despair(绝望)。
　　2. The tobacco industry openly pushes its product as something to lift your mood(精神) and soothe(缓解) anxiety. But the short-term feel-good effect may mask(掩盖，面具) the truth: that smoking may worsen or even trigger anxiety disorders(不安), panic(恐慌) attacks and depression, perhaps even schizophrenia(精神分裂).
　　3. Cigarettes and mental illness(精神疾病) have always tended to go together. An estimated 1.25 billion people smoke worldwide. Yet people who are depressed or anxious are twice as likely to smoke, and up to 88 per cent of those with psychotic disorders such as schizophrenia smokers. A recent American survey concluded that around half of all cigarettes burn in the fingers of those with mental illness.
　　4. But the big question is why? The usual story is that the illness comes first. Mentally ill people take up smoking, or smoke more to alleviate some of their distress. Even when smoking seems to start before the illness, most doctors believe that early but invisible symptoms of the disorder spark the desire to light up. But perhaps something more sinister is going on.
　　5. A growing number of researchers claim that smoking is the cause, not the consequence of clinical depression and several forms of anxiety. “We know a lot about the effects of smoking on physical health, and now we are also starting to see the adverse effects in new research on mental illness,” says Naomi Breslau, director of research at the Henry Ford Health Care System in Detroit.
　　6. Breslau was one of the first to consider this heretical(异端的) possibility. The hint came from studies, published in 1998, which followed a group of just over 1,000 young adults for a five-year period. The 13 per cent who began the study with major depression were around three times more likely to progress from being light smokers to daily smokers during the course of the study, though there was no evidence that depression increased the tendency to take up smoking. But a history of daily smoking before the study commenced roughly doubled the risk of developing major depression during the five-year period Smoking, it seems, could pre-date(提早，预先)illness.
　　7. At first Breslau concluded that whatever prompts(促使) people to smoke might also make them depressed. But as the results of other much larger studies began to back the statistical link(统计学联系), she became more convinced than ever that what she was seeing were signs that smoking, perhaps the nicotine itself, could somehow affect the brain and cause depression.
　　8. One of these larger studies was led by Goodman, a pediatrician(儿科医生). She followed the health of two groups of teenagers for a year. the first group of 8,704 adolescents were not depressed, and might or might not have been smokers, while the second group of 6,947 were highly depressed and had not been smokers in the past month. After a year her team found that although depressed teenagers were more likely to have become heavy smokers, previous experimentation with smoking was the strongest predictor of such behaviour, not the depression itself. What is more important is that teenagers who started out mentally fit but smoked at least one packet per week during the study were four times more likely to develop depression than their non-smoking peers. Goodman says that depression does not seem to start before cigarette use among teens. “Current cigarette use is however, a powerful determinant of developing high depressive symptoms(症状).”
　　9. Breslau, too, finds that smokers are as much as four times more likely to have an isolated(孤立的) panic attack and three times more likely to develop longer-term panic disorder than non-smokers. It’s a hard message to get across, because many smokers say they become anxious when they quit,(戒掉) not when they smoke. But Breslau says that this is a short-lived effect of withdrawal which masks the reality that, in general(总的来讲), smokers have higher anxiety levels than non-smokers or ex-smokers(不在抽烟者).
