So, while the saying may be that substance abuse “runs in the family,” a whole list of other risk factors in addition to genes come into play to determine whether a person gets hooked. These include biological factors, such as genetics, one’s age, or the presence of other diseases, as well as environmental factors, such as diet, stress, or peer pressure. Neither John nor Keith shares their parent’s battle with addiction, but the twins know that their family genetics can increase their risk of addiction. 
因此,尽管有药物滥用是家族遗传之说,但除了基因,还有许多其他风险因素共同决定一个人是否会成瘾。这些因素包括生物学因素,如遗传、年龄或其他疾病的影响;环境因素,如饮食、生活压力或同辈之间的压力。约翰和基思都未继承父亲(或母亲)的酒瘾,但他们知道家族遗传可能会增加他们成瘾的风险。
It may be hard to see how a tiny piece of DNA could influence the risk of becoming addicted. The fact is, however, that scientists have identified several genes that can do just that. In reality, every gene comes in different forms, and researchers have discovered that some of these variants can make people more likely to abuse marijuana, heroin, cocaine and other illegal, as well as legal, drugs. Certain genes can actually influence the way in which a person responds to drugs.
也许一段小小的DNA就能影响吸毒成瘾的风险是很难想象的。然而事实上,科学家已经证实好几种基因能够做到这样。实际上,每个基因以不同形式存在着,研究者发现其中一些变体使人们更有可能滥用大麻、海洛因、可卡因和其他非法和合法的药物。某些基因事实上能影响一个人对药物的反应方式。
First identifying which genes are involved in the addiction process, then determining which forms of those genes increase the risk---and which are protective---is serious business. Genetic information will help to identify who may be at greater risk for addiction, and suggest targets for innovative medications to treat those who become addicted. And, just as important, knowing one’s genetic risks, like John and Keith Crawford do, helps in making smart choices. 
首先辨别哪些基因参与成瘾的过程,然后确定这些基因的哪些形式会增加上瘾的危险,这是一项复杂的工作。基因形式将有助于确认哪些人更容易成瘾,并有的放矢地研制创新药物来治疗哪些上瘾者。同样重要的是,像约翰和基思那样了解自身的基因风险,可以对做出明智的选择有帮助。
