新研究提示酗酒同时嗜烟者精神状态更差, 这可以部份地归结于尼古丁的长期作用。密执安大学瘾研究中心的詹尼弗玻璃博士告诉路透社健康说: “酗酒并嗜烟者风险高的多, 抽烟与智商和思维能力成负相关” 。这一发现似乎与直觉相反, 因为许多吸烟者证实抽烟提神并集中注意力。的确, 研究表示尼古丁的直接作用是兴奋, 然而它的慢性作用却相反。此研究发表在 <<药物与酒精依赖>> (Drug and Alcohol Dependence)的网络版上。

Smoking Can Drop IQ And Thinking Ability

The poorer mental function seen among alcoholics, many of whom also regularly smoke cigarettes, may be partially due to the long-term effects of nicotine, new research suggests. "People who are also smokers are at a much higher risk," Dr. Jennifer M. Glass, of the University of Michigan's Addiction Research Center, told Reuters Health. In her study, "cigarette smoking was negatively related to IQ and thinking," she said. This finding may seem counterintuitive, since many smokers attest to feeling more alert and focused after smoking. Indeed, research shows that improved mental functioning is one of the immediate effects of nicotine exposure. Chronic smoking, however, is known to have the opposite effect. (See Story from Reuters)
