Use of the illegal drug named Ecstasy(MDMA)(一种迷幻药, 俗称摇头丸)has increased alarmingly in Britain over the last few years, and in 1992 the British Medical Journal claimed that at least seven deaths and many severe adverse reactions have followed its use as a dance drug. 14 deaths have so far been attributed to the drug in Britain although it is possible that other drugs contributed to some of those deaths. While it is true that all drugs by their very nature change the way in which the body reacts to its environment and are therefore potentially dangerous, it is still unclear whether casual use of Ecstasy is as dangerous as authorities believe. What is certain is that the drug causes distinct changes to the body which, unless understood, may lead to fatal complications in certain circumstances. In almost all cases of MDMA related deaths in Britain, overheating of the body and inadequate replacement of fluids have been noted as the primary causes of death. Yet in the US, studies appear to implicate other causes. It seems that normal healthy people are unlikely to die as a result of taking MDMA, but people with pre-existing conditions such as a weak heart or asthma may react in extreme ways and are well advised not to take it. Not all physical problems associated with the drug are immediate. Medium term and long term effects have been reported which are quite disturbing, yet not all are conclusively linked to the drug’s use. Medium term effects include the possibility of contracting the liver disease hepatitis, or risking damage to the kidneys. However, animal studies show no such damage, although it is readily admitted by researchers that animal studies are far from conclusive since humans react in different ways than rats and monkeys to the drug. Perhaps the most damning evidence urging against the use of Ecstasy is that it is undoubtedly an addictive substance, but one that quickly loses its ability to transport the mind, while it increases its effect upon the body. Yet, unlike the classic addictive drugs, Ecstasy does not produce physical withdrawal symptoms. In fact, because one becomes quickly tolerant of its effect on the rind, it is necessary to give up its use for a while in order to experience again its full effect. Any substance which produces such a strong effect on the user should be treated with appropriate respect and caution.
It is implied in the passage that the conclusion drawn from MDMA studies on animals______.
选项
A、cannot provide absolute proof of the effect of the drug on humans
B、shows damage to the kidneys
C、suggests the use of Ecstasy increases the risk of contracting the liver disease hepatitis
D、has been overlooked
答案
A
解析
推理题。文章提到:However,animal studies show no such damage,although it is readily admitted by researchers that animal studies are far from conclusive since humans react in different ways than rats and monkeys to the drug.通过这句话可知,动物实验并没有得出确 切的结果,因为人对毒品的反应与动物对毒品的反应是不同的。所以,答案为A。
