It would be irresponsible to answer the question of "How long does Demerol
stay in your system?" without at least mentioning the possibility of Demerol abuse and addiction. If you are searching the internet for information about Demerol drug testing, there is a good chance that you may have a problem. Your healthcare provider is a great place to start when searching for help for Demerol addiction or abuse. He or she will be able to help you deal with such problems (hopefully in a nonjudgmental way) or may suggest other resources for you.
