Well, for one, your body can build up a tolerance, so the more you use the larger dose you need to get the same effect.

Secondly, you could become dependent on them.

其次，你可能會對他們產生依賴。

In fact, your body creates natural opioids that are released when you hurt yourself.

事實上，你的身體會產生天然的阿片類藥物，當你傷害自己時，這些藥物就會被釋放出來。

But if you habitually use painkillers, your body stops producing its own and relies on the drugs instead.

但如果你習慣性地使用止痛藥，你的身體就會停止產生自己的止痛藥，而依靠藥物來代替。

If you try and stop, then the body goes through withdrawal.

如果你試圖停止，那麼身體就會經歷戒斷。

考慮到這一點。

In 2012 there were 259 million prescriptions written for opioid painkillers, nearly enough for every American adult and child to have their own bottle of pills.

2012年有2.59億張阿片類止痛藥的處方，幾乎足夠每個美國成年人和兒童擁有自己的藥瓶。
