智商高的女性更易在三十多歲時吸毒

Women with high IQs are far more likely to take cannabis, cocaine and ecstasy in their thirties, a study has found.

Researchers think they are more open to new experiences so are more willing to experiment with illegal substances.

The study by Dr James White from Cardiff University found that women with higher than average IQ scores were twice as likely to have taken drugs such as cannabis, cocaine, ecstasy and amphetamines in their thirties as those with lower scores.

Dr White looked at the records of 8,000 people dating back to the 1970s who had all had their IQ measured at the ages of five and ten.

They had also answered questions about whether they had taken any drugs when they were 16 and again when they were 30.

The study, published in the Journal of Epidemiology and Community Health, found that women aged 30 who had higher than average IQs – between 107 and 150 - were more than twice as likely to have used illegal substances compared to those with scores of less than 95.

An average IQ score is 100.

Men with high IQ scores were 50 per cent more likely to have used amphetamines, ecstasy, and several illicit drugs than those with low scores – so the link was not as strong as amongst women。

Dr White said: "If we were to speculate it could be that people with high IQs tend to be more open to new experiences."

"They also don't think they are at risk by just trying once or twice."據英國《每日郵報》11月15日報道，研究顯示，高智商的女性更容易在三十幾歲時沾染大麻、可卡因和搖頭丸。

研究人員認爲，她們對新的經歷體驗的接受程度更高，所以更加樂於去嘗試這些非法藥品。

來自卡迪夫大學的詹姆斯•懷特博士研究發現，智商超過平均水平的女性在三十多歲時吸食大麻、可卡因、搖頭丸和安非他命等非法藥品的可能性是較低智商的女性的兩倍。

懷特博士查看了8000人的記錄，一直追溯到上世紀70年代，這些人都在五歲和十歲時做過智商測試。

他們也就是否在十六歲時吸食過任何毒品以及三十歲時的相關情況回答了一些問題。

刊登在《流行病學與公共衛生雜誌》上的研究顯示，三十歲的智商超出平均水平的女性——IQ測試得分大約在107到150分之間——使用非法藥品的可能性是那些智商水平測試得分低於95的女性的兩倍。

平均智商分數是100分。

而高智商男性比較低智商的男性服食安非他命、搖頭丸等違禁藥物的可能性則只高出50%——關聯性遠不如女性那麼密切。

懷特博士說：“如果我們推測一下，可以得出，高智商的人羣對新的經歷體驗接受度更高，也更加開放。”

“他們並不覺得僅僅嘗試一兩次是在冒險。”
