I took 4-5 50mg demmerol tabs about 3-4 weeks ago in a weeks time frame and 2-3 tylenol 3 a couple weeks ago and that is all I have taken I have a hair test this week and want to know if that would be enough for me to test positive for codein and my other question is will demerol make me test pos. for morphine, I know it is not the same but they are very similar! Any info greatly appreciated!
