I doubt they will test the placenta but if they suspect drug use they may test the baby. I don't know for sure how long cocaine stays in but its over a few days span. If you are pregnant and doing drugs or anyone you know for you sake and the baby's please get professional help! I'll be praying for you.
They can drug test your placenta and may. If you are a smoker and your placenta is off color. Or if there is something wrong with your baby after birth. Which of the trimesters are you? What drug or drugs are in your system? An expecting mother can be admitted to a detox clinic. They will dose you and drug test you if you want to lessen the negative effects on your baby. After your deliver they will continue to detox you and the baby.
Monzo sweetie, get some help. For you and the baby. If your biggest concern at this point in your pregnancy, is if you will be detected as a drug user. This is not meant to be judgmental, at all. This is from my heart dear. Can you see that you are truly loved, and blessed to be considered a candidate for becoming a Mother. Whatever you, or your life have been. YOu have the power to build a human being, the one God is giving you.God is giving you another chance. Grab onto it, like a life jacket, and Experience the Love, that is awaiting. Do this for yourself, Do this for the little piece of you that you are bringing into the world.Do this for the human race, and you will not regret it. Please get some help. You are a child of the Universe, and You are loved.
All I have to say is wow. How could you not seek some sort of relief from drugs for that precious little baby that is so helpless?
