毕竟，生命本身就是个瘾头，很少人会自愿放弃。

Life, after all, is an addiction that few people give up willingly.

因此，医疗之道应设法打断其瘾头或继续供应毒剂。

Medicines should therefore be designed to break the addiction or supply the poison.

一位朋友的女儿今年12岁，她对文字短讯上瘾了，可知道那瘾头有多严重。

It can start at a very young age. I have a friend of mine who has a 12 - year - old daughter and shes addicted to text messaging.

任何研究瘾头的人都能告诉你，毒品只是开门(和化学反应)的钥匙，开启一个现实生活的常规(像信用卡卡债)不再当道的世界。

As any addiction researcher can tell you drugs are merely keys that unlock doors (and chemical reactions) opening up a world where the normal rules of reality (like credit card bills) don't hold sway.
