| Use of the illegal drag named Ecstasy
(MDMA) 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 mind, it is necessary to forgo 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. |
