      Why is smoking so difficult to give up? Inhaling a puff of smoke from a cigarette sends nicotine molecules zooming up into the brain within seconds. Then the nicotine grabs hold of receptors on brain cells and releases dopamine, the brain's feel-good chemical, bringing feelings of pleasure and comfort。
  Besides dopamine, smoking also activates the release of other molecules in the brain that make you feel good, including chemicals called endogenous opioids, according to 2004 research from the University of Michigan。
  And cigarette companies haven't been making it any easier for people to kick the habit. Over the past decade, companies have made changes to the design and ingredients in cigarettes to make them more alluring to first-time smokers, and more addictive for long-time smokers。
  These changes include adding ammonia to the tobacco, which converts nicotine into a form that gets to the brain faster, as well as adding holes to cigarette filters that allow people to inhale smoke more deeply into their lungs. Other additions, such as sugar and "moisture enhancers," reduce the dry, burning sensation of smoking, making it a more pleasant experience - especially for new cigarette smokers。
  When you stop smoking, and your nicotine receptors stop being activated. Essentially, you're not getting as much dopamine as you're used to, which can cause feelings of withdrawal. In fact, a 2002 study in the Journal of Consulting and Clinical Psychology showed that people who had quit cold turkey had lingering feelings of depression and tension 31 days later。

 

我的译文

 为什么吸烟难戒?从香烟中,吸入一口烟,会释放尼古丁分子,几秒钟就大量进入大脑。随后,尼古丁控制在大脑细胞上的受体,并释放多巴胺——让大脑感到愉悦的化学物质,使人感到愉快、舒适。
 除了多巴胺之外,吸烟还使得大脑中的其他分子释放,使人感觉良好。这包括一种叫内源性阿片类的化学物质,该物质来源于2004年密西根大学的研究。
 烟草公司一直做着努力,让人们更难摆脱烟瘾。在过去的几十年里,这些公司改良香烟的设计,改进了成分,使得烟草对初次抽烟的人来说,更具诱惑力;对长期抽烟的人来说,更易上瘾。
 当一个人戒烟,他的尼古丁受体被抑制。最重要的是,他没有得到如同往常那样的多巴胺量,这使得他产生放弃戒烟的念头。事实上,2002年,在《循证和临床心理学期刊》上的研究表明,人如果放弃吃冷火鸡,紧张失望的感觉将持续31天。
