我身边真实的例子。
第一，邻居老人，年轻时受伤，然后布洛芬就停不下来了，他太太说每天吃“一把”。
第二，我儿子的同学（一流名校）每天三十多片非处方止痛片，不吃就无法上课。
也许有人会咬文嚼字区别上瘾和药物依赖，但我觉得没什么区别。
英文这样说：
An individual may begin taking Ibuprofen in order to manage mild to moderate physical pain. This may lead to the risk of developing a tolerance or dependency on the drug due to feeling as though they cannot function normally without the Ibuprofen.
For some people, Ibuprofen may be a way of “numbing” not only physical pain, but emotional pain as well.
For men and women who have suffered a traumatic event or have unresolved emotional issues, their dependency on Ibuprofen may result out of a psychological need to anesthetize pain.
